What is Butylhydroxytoluene?

Butylhydroxytoluene is an excellent general-purpose phenolic anti-oxidant. It is non-toxic, non-flammable, non-corrosive, as well as likewise has excellent storage room protection. It can hinder or postpone the oxidative degradation of plastics or rubber to extend the life span.Butylhydroxytoluene is a phenomenal antioxidant additive for different oil products. It is generally made use of in various lubricating oils, gas, paraffin as well as numerous resources oils to avoid the acid worth or viscosity of fueling oil oils and also gas oils from improving. As a food anti-oxidant along with stabilizer in food-grade plastics along with packaged foods, it can delay food rancidity. It can furthermore be made use of for polyethylene (PE), polystyrene (PS), PP (polypropylene), polyvinyl chloride, abdominal material, polyester, cellulose product in addition to foamed plastics (particularly white or light items), food Quality plastics, all-natural rubber, man-made rubber (styrene-butadiene, nitrile, polyurethane, butadiene rubber, and so on), pet as well as veggie oils, and also foods as well as also cosmetics having pet as well as vegetable oils. The reference dose is usually 0.1%-1.0%.

Butylhydroxytoluene Uses

Butylhydroxytoluene is a common phenolic antioxidant, which can prevent or delay the oxidative degradation of plastics, rubber, polyurethane, acrylate as well as latex products to lengthen the life span. Antioxidant BHT can hinder copper damages, and can be utilized along with anti-ozone and wax to stop damage to chemical items triggered by different climate aspects. Antioxidant BHT can additionally be utilized as a stabilizer for post-treatment and storage space of chemical items.

Butylhydroxytoluene can protect against the acid worth or viscosity of lubricating oil and also gas oil from raising. Antioxidant BHT is widely utilized in wind turbine oil, transformer oil, hydraulic oil, brake oil, pin oil and also precision equipment oil, paraffin anti-adhesive agent and also area temperature level anti-oxidant. Butylhydroxytoluene can be added directly or right into the mommy liquor into the item. In order to boost the anti-oxidation performance of the product as well as lengthen its service life.

Butylhydroxytoluene itself has no strange scent as well as will certainly not bring peculiar odor and also odor to the product. It can be made use of as an anti-oxidant for feed or as a preservative. It has greater safety and security, can postpone food rancidity, and improve the storage space of food oil. security. Antioxidant BHT is frequently utilized in pet and vegetable oils and foods consisting of animal as well as vegetable oils.

Today, the domestic and foreign markets have higher and higher needs on the product top quality of Butylhydroxytoluene, as well as the industrial sector offers top priority to the use of food-grade BHT to guarantee the high quality of its products.

Production Method of Butylhydroxytoluene

(1) Put p-cresol and tert-butanol in a molar ratio of 1:1.1 right into the activator and warm to liquify. Under the action of stimulant phosphoric acid, respond under strong stirring at 65-70 ° C; after the reaction is finished, the response item is first washed with 10% sodium hydroxide option up until it is alkaline, and afterwards washed with water until it is neutral; remove the solvent as well as recrystallize with ethanol That is the finished item.
CH3C6H4OH+( CH3) 3COH [H3PO4] → BHT.

( 2) Pass isobutylene into a blend of 98% p-cresol and also 2% concentrated sulfuric acid, and react at 65-70 ° C for 5 hrs; clean off the acid with hot water at 60 ° C, and after that clean with 10% NaOH as well as hot water together up until Neutral too rough. Liquify the crude product in 50% warm ethanol, include 0.5% thiourea, filter while hot, rotate dry, and also dry to acquire the finished product with a yield of 90% -95%, a pureness of 99.5%, as well as a melting point of > 69.5 ° C

. In industry, the main as well as complementary towers are attached in collection. First add p-cresol as well as catalyst right into the primary tower and also the complementary tower, the temperature level of the primary tower is controlled at 65-80 ° C, and also the temperature level of the auxiliary tower is controlled at 50-70 ° C. The isobutene gas is introduced from all-time low of the major tower, as well as the majority of it reacts with p-cresol in the main tower, and also the remaining part appears from the top of the main tower and also enters the bottom of the supporting tower to additionally react with p-cresol. The response cycle of the main tower is managed within 4-5 hours. When the response is over, stop the flow of isobutene gas, include 20% NaOH option, and bubble with pressed gas. The counteracted alkylated item was separated through a purification column (8 academic plates) to obtain a crude product. The last is dissolved in 95% ethanol, ion-exchanged to remove not natural salts, cooled to 10-20 ° C for condensation, separated, as well as vacuum-dried to get an item with a melting point above 69 ° C.
CH3C6H4OH+( CH3) 2C CH2 [H2SO4] → BHT.

Application of Butylhydroxytoluene

Prepare a sericin moisturizing hand cream, comprising the following raw materials in parts by weight: 13 parts of sericin, 8 parts of sodium stearate, 1 part of aloe mud, 3 parts of sorbitol, 2 parts of vitamin E, 1 part of sheep oil, 2 parts of avocado oil, 19 parts of polydimethylsiloxane, 3 parts of polypropylene alcohol, 12 parts of allantoin, 12 parts of Butylhydroxytoluene, 1 part of wax oil, 40 parts of deionized water, and 1 part of leveling agent.
