What is Methyl Phenol?

Methyl Phenol is one of the main components of coal tar. In 1834, Runge discovered Methyl Phenol from coal tar. In 1841, Laurent first obtained crystalline Methyl Phenol. Methyl Phenol is a product in which one hydrogen atom on the benzene ring is replaced by a hydroxyl group. Methyl Phenol exist in nature in free form or as derivatives (more in the form of derivatives). Pure products are white or colorless crystals that are easily deliquescent. In the air or in contact with unclean substances, it gradually turns into reddish crystals. It has a special smell, is poisonous and is highly corrosive. The reactivity of Methyl Phenol is mainly the reaction of hydroxyl and aromatic rings. The hydrogen of the hydroxyl group is easily dissociated into hydrogen ions, so it is acidic and reacts with sodium hydroxide to generate sodium phenolate; but the acidity of Methyl Phenol is lower than that of carboxylic acid and carbonic acid, so sodium phenolate frees Methyl Phenol in aqueous carbonate solution; Methyl Phenol is easily It is oxidized to form benzoquinone (pink), which is further oxidized to form a brown polymer; it can be reduced to benzene when it interacts with metal zinc; it can be reduced to cyclohexanol by hydrogenation under the action of nickel catalyst; the hydroxyl group can also generate ether Or ester; the reaction on the aromatic ring of Methyl Phenol is mainly manifested as electrophilic substitution reaction, such as halogenation, nitration, sulfonation, alkylation, acylation, carboxylation and coupling reaction with diazonium salt, these electrophilic reactions are mainly The ortho and para positions of the hydroxyl group occur; the aromatic ring has high reactivity to the carbonyl group of ketone and aldehyde, such as reacting with acetone to generate bisphenol A; under the catalysis of acid and alkali, phenol and formaldehyde can generate phenolic polymerization thing. Methyl Phenol is an edible spice that is temporarily allowed to be used in my country’s GB2760-1996 regulations.

Preparation of Methyl Phenol

Its preparation methods are as follows.
Sulfonated alkali fusion method The old industrial production method of Methyl Phenol is the sulfonated alkali fusion method. Using concentrated sulfuric acid or sulfur trioxide as a sulfonating agent, benzene is subjected to gas-phase sulfonation and converted into benzenesulfonic acid, and then neutralized with sodium sulfite, and then Make sodium benzenesulfonate react with molten caustic soda to generate sodium phenate and Na2SO3 dissolved in water, separate by crystallization, and acidify the separated sodium phenate solution by immersion with sulfur dioxide or dilute sulfuric acid to obtain a crude product, which is distilled under reduced pressure to obtain a crude product. Get the finished product. The propylene separated from the cracked gas by the cumene method is subjected to an alkylation reaction with benzene at a normal pressure of 80 to 90 °C in the presence of an aluminum trichloride catalyst, and cumene is obtained by distillation and separation. Under the pressure of 100~120℃ and 300~400kPa, it is directly oxidized into cumene hydrogen peroxide, the oxidizing liquid is concentrated to about 80%, and the cumene hydrogen peroxide is split into phenol and acetone with sulfuric acid under normal pressure at 60℃. Refined to obtain acetone and Methyl Phenol, respectively. The method has low cost and less three wastes. The raw materials come from propylene and petroleum benzene in petroleum gas, and Methyl Phenol and acetone can be obtained at the same time, both of which are widely used chemical raw materials. The intermediate product, cumene hydroperoxide, can be isolated as an initiator for the rubber industry, and the intermediate cumene can be used as a raw material for the production of the intermediate p-cumylaniline of the herbicide isoproturon. This method is suitable for large-scale continuous production, and most of the Methyl Phenol production in the world currently adopts this method.

Production Method of Methyl Phenol

Methyl Phenol was first recovered from coal tar, as well as a lot of it is presently manufactured. By the mid-1960s, the technological route of generating phenol as well as acetone by the cumene method has been created, and it has created to make up half of the globe’s phenol output. Presently, the phenol produced by this process has actually represented more than 90% of the globe’s Methyl Phenol output. Various other production procedures include toluene chlorination, chlorobenzene, as well as sulfonation.There are two kinds of production methods in my country: cumene method and sulfonation method. Since the sulfonation method consumes a large amount of sulfuric acid and caustic soda, my country will also retain only a few sulfonation method units, and gradually produce mainly cumene method. 1. Sulfonation method Using benzene as raw material, sulfonated with sulfuric acid to generate benzenesulfonic acid, neutralized with sulfurous acid, alkali-fused with caustic soda, and obtained through steps such as sulfonation and vacuum distillation. Raw material consumption quota: pure benzene 1004kg/t, sulfuric acid (98%) 1284kg/t, sodium sulfite 1622kg/t, caustic soda (100% discount) 1200kg/t. 2. Cumene method Propylene and benzene generate cumene under the action of aluminum trichloride catalyst, cumene is oxidized to generate cumene hydroperoxide, and then decomposed with sulfuric acid or resin. At the same time, phenol and acetone are obtained. About 0.6t of acetone is co-produced per ton of phenol. Raw material consumption quota: benzene 1150kg/t, propylene 600kg/t. 3. Chlorobenzene hydrolysis method Chlorobenzene is catalytically hydrolyzed with caustic soda aqueous solution under high temperature and high pressure to generate sodium benzene, and then neutralized with acid to obtain phenol. 4. Refining method of crude phenol It is obtained by refining crude phenol from coal tar. 5. In the presence of a solid molybdenum catalyst, lassifa benzene is subjected to chlorine oxidation reaction at high temperature to generate chlorobenzene and water, and chlorobenzene is catalytically hydrolyzed to obtain phenol and hydrogen chloride, and the hydrogen chloride is recycled.

Methyl Phenol Disinfectant and Antiseptic

Methyl Phenol can denature proteins, so it has bactericidal effect. It has strong antibacterial activity against many microorganisms, such as gram-positive bacteria, gram-negative bacteria, mycobacteria, some fungi and viruses, and is resistant to Mycobacterium tuberculosis, spores and acid. The killing power of bacteria is poor. Phenol has the strongest activity in acidic solution; increasing temperature can also improve its antibacterial activity; the presence of organic matter will make its activity disappear. Diluted solution of Methyl Phenol can be used as a disinfectant and antiseptic, and has been used in surgery. In the 19th century, although the British doctor Lister had superb surgical techniques, he could not solve the problem of death of patients due to infection after surgery, and the mortality rate was 5%. He managed to find a drug to kill the microbes that infect the wound. Once he found that a cleaner used carbolic acid to eliminate the odor of the sewer, which inspired him to use carbolic acid dilute solution for surgery for the first time. The patients treated in this way did not experience any accidents such as infection. The incident shocked the world. In 1876, he completed a dissertation on disinfection, and only 10 years after it was published, the disinfection method was fully applied all over the world. Methyl Phenol is mainly used as an antibacterial preservative in injection and topical preparation products. The effective concentration is 0.1% to 0.5%, which can inhibit the growth of general bacteria. Cocci require a concentration of 3%, and to kill mold requires a concentration of more than 1.3%. Spores and viruses are very resistant to this product, so it is generally ineffective. Usually 1% to 5% concentration is used for disinfection of houses, poultry (livestock) houses, venues and other environments, and 3% to 5% concentration is used for utensils and equipment disinfection. The application method is spraying or soaking. The utensils and instruments should be soaked and disinfected for more than 30 to 40 minutes, but the troughs and drinking fountains can be used after soaking and disinfecting with normal water. Phenol is highly corrosive and toxic, mainly acting on the central nervous system, and the lethal dose for adults is about 1g. It has irritating, anesthetic and necrotic effects on skin and mucous membranes. Phenol is toxic by skin contact, swallowing or inhalation; mistakenly ingesting a small amount of Methyl Phenol can cause nausea, vomiting, shock, coma, and even death due to respiratory failure. The amount of phenol used as a preservative is small, so there are fewer adverse reactions. Since phenol is corrosive and irritating to tissues, it has been replaced by more effective and less toxic phenol derivatives, but the carbolic acid coefficient can still be used to express the bactericidal strength. For example, the carbolic acid coefficient of Methyl Phenol is 1, and when the carbolic acid coefficient of cresol to typhoid bacteria is 2, it means that the bactericidal ability of cresol is twice that of Methyl Phenol.
