What is Heptaldehyde?

N-Heptanal, also called heptanal, is miscible with ethanol and ether, soluble in 60% ethanol, and a little soluble in water. It can be reduced to n-heptyl alcohol and oxidized to n-heptanoic acid, which exists in castor oil. N-Heptanal can be used as a basic material for organic synthesis, such as the synthesis of δ-laurolactone. Lactone is a vital organic substance and intermediate and has broad application and advancement potential customers in the fields of scent and pharmaceutical synthesis.

For instance, γ- and δ-lactones have been utilized in high-end cosmetics, food and tobacco industries, and due to the fact that lactones are the main components of all-natural butter flavor, and all-natural butter consists of a large amount of pet fat, excessive inhalation can quickly cause cardiovascular disease. Some established countries utilize vegetable oil to add lotion flavor as margarine for usage in the food industry, and the flavor is virtually the same as all-natural cream. Using this brand-new top notch lotion flavor can decrease the amount of cream in food and play a vital role in securing individuals’s health.

Heptaldehyde Uses

1. Due to the fact that it originates from castor oil or among the bosom items of ricinoleic acid methyl ester, Heptaldehyde is mainly made use of as a resources for the synthesis of perfume-α-amylcinnamic aldehyde and corresponding homologous derivatives. The dosage for various types of edible tastes is 1.2 ~ 4.9 mg/kg. Utilized as soap taste, detergent taste, perfume flavor, lotion flavor, and so on

2. Heptaldehyde is a vital resources for artificial flavors and is also a basic material for pharmaceuticals, organic synthesis and rubber products.

Heptaldehyde Application

Heptaldehyde can be made use of to prepare orange essence and climbed essence, and can on top of that be made use of to prepare n-heptanoic acid, which is made use of as a resources for all-natural synthesis. Situations of its applications are as complies with:

1. Preparation job of 2-heptylcyclopentanone.
Under the work of sodium hydroxide energizer, cyclopentanone, n-heptanal and stage transfer energizer respond at 50 ~ 80 ℃ for 8 ~ 10 hours, adjust the pH well worth to 6 ~ 7, include toluene, and mix at 100 ~ 120 ℃ Till bid farewell to water is created, the ended up product is absolutely obtained utilizing cleansing and drying. The molar proportion of cyclopentanone and Heptaldehyde is (1 ~ 1.3):1. Choosing β-cyclodextrin as a phase transfer energizer can raise the response price and promote cross-condensation.

2. Preparation job of δ-laurolactone.
Include the sticking to jobs:
( 1) Condensation and dehydration: Contain 0.5% to 20% mass section of salt hydroxide service, cyclopentanone and stage transfer energizer right into a three-necked flask, raise the temperature to 10 to 50 ° C, contain Heptaldehyde dropwise, and surface area dripping in 1 to 4 hours. (The molar percentage of cyclopentanone to n-heptaldehyde is 1:1 to 5:1). Given that the job of the condensation response in between aldehydes and aldehydes is above the task of the condensation responses in between aldehydes and ketones, an extra of ketones is asked for to stop excessive side responses.

After that respond at a consistent temperature level of 10 to 50 ° C for 1 to 3 hours, fantastic, and lower the impacts of with acetic acid to make the mix pH=5 to 6. Enable stand and different right into layers, remove the fluid layer with an extractant, integrate the organic stages, cleaning with 5% NaHCO3 and saturated NaCl fluid treatment, transfer to a gadget with a water separator, comfortable and completely dry. After cooling off, neat, completely dry with anhydrous Na2SO4, evaporate the extractant under normal tension of 105, lower the anxiety and anxiousness to 350 ~ 450 for purification, and build up the 2-heptenecyclopentanone part at 90-100 ° C/350 ~ 450 Pa.

( 2) Hydrogenation: Consist Of 2-heptenecyclopentanone to the activator in N2 ambience, after that consist of ion exchange resin-supported palladium energizer and solvent, and existing H2 at typical tension and 10 to 50 ° C till the response no longer absorbs Hydrogen stops. Washing the ion exchange material kept palladium stimulant with solvent. Revolving vaporize to eliminate the solvent in the feedback, reduced the anxiety to 250Pa-270Pa for filtering system, and gather the part 2-heptylcyclopentanone at 75-85 ° C/250 -270 Pa.

( 3) Oxidation: Include methanol as the solvent to the three-necked flask, afterwards consist of 2-heptylcyclopentanone and acid accelerator, mix and decrease the oxidant at 20 to 60 ° C. Consistently made use of oxidants are hydrogen peroxide and oxygen, which are significantly exceptionally easy to guard the setup. However, the reaction selectivity and conversion cost of using oxygen as the oxidant are generally decreased, so using hydrogen peroxide is especially essential. After the dropwise improvement, preserve the temperature level degree constant at 20-60 ° C, interest to track the reaction to verdict, include water, continue blending, tidy with water, combat with 5% NaHCO3, clean the liquid layer with toluene, integrate the all-natural stages, and come down to eliminate the toluene in the natural layer under normal tension of 105Pa., manage the temperature degree not to go beyond 60 ° C, and the residue is raw δ-laurolactone.

( 4) Refining of the raw product: Condense the above crude thing making use of a molecular filtration tool, take care of the temperature degree to 120-130 ° C and the pressure to 300Pa, and gather the fit to be linked product, which is δ-laurolactone.

Heptaldehyde Preparation

Step 1: Synthesis of benzimidazole: Consist of 0.1 mol o-phenylenediamine and 0.15 mol formic acid right into a 100 mL round-bottomed flask, warm to reflux at 90 ° C for 2 h, cool, and take advantage of 10% NaO with mixing: The H service was gotten used to rather alkaline. After suction filtering system and water recrystallization, white half-cracked crystals were gotten. The return was 88%, mp 171 ~ 173 ℃.

Task 2: Synthesis of 1,3-dimethylbenzimidazole salt: 0.02 mol of benzimidazole was liquified in an ethanol option (8 mL) having 0.02 mol of salt ethoxide, and 0.05 mol was added Methyl iodide and 20 mL benzene were reacted at reflux temperature level for 18 hours, cooled, filteringed system, and the strong was recrystallized with absolute ethanol or acetone to get 4.39 g of white strong, return 80%, mp 201 ~ 202 ° C. Action 3: Synthesis of 1,3-dimethyl-2-hexylbenzimidazolidine: Under N2 gas protection, 0.02 mol 1,3-dimethyl-2-H benzimidazole salt was added to 0 in collections. 04 mol of Grig nard reagent in tetrahydrofuran alternative, mix for 15 hours after enhancement, evaporate the solvent, significance the residue with cyclohexane (40 mL × 3), totally dry over magnesium sulfate, and evaporate the cyclohexane to acquire anemic Oily product, bp 95 ~ 96 ℃/ 2. 50 kPa.

Idea 4: Synthesis of n-heptaldehyde: Under N2 gas defense, add 0.02 mol 1,3-dimethylbenzimidazole salt in sets to the tetrahydrofuran remedy of 0.04 mol Grig nard reagent in a warm water bathroom, Mix the feedback in a comfy water restroom at 50 ~ 70 ° C for 16 ~ 18 hours. Include 5% hydrochloric acid liquid service to adjust the pH value to 3 ~ 4, continue mixing in an enjoyable water restroom for half an hour, vaporize the solvent, and extract with ether. The essence is cleansed with 5% NaHCO3 solution and water especially, dried with anhydrous MgSO4 overnight, and evaporated. Diethyl ether is distilled to gather the section at 151 ~ 152 ° C, which is Heptaldehyde, with a return of 65%.
