It is mainly used to prepare jasmine, peach, apricot, raspberry, strawberry, apple, grape, plum, banana, cherry, pear, pineapple, papaya, cream and other flavors. benzyl acetate is an edible spice temporarily allowed to be used in China's regulations. it can be used to prepare fruit flavor flavors such as bayberry, apple, pineapple, grape, banana, strawberry, etc. the dosage is 760 mg/kg in chewing gum according to normal production requirements. 34 mg/kg in candy; 22 mg/kg in baked food; 14 mg/kg in cold drinks; 7.8 mg/kg in soft drinks. 1. Use of spices. Benzyl acetate is the main component of jasmine and other extracts. It is an indispensable spice in the preparation of fragrance and fragrance. Because of its low price, it is mostly used for soap and other industrial flavors. It is often used in large quantities in jasmine, white orchid, hosta, yuxia incense and narcissus, and can also be used in small quantities in raw pears, apples, bananas, mulberry and other edible flavors. 2. Use of solvent benzyl acetate dissolves 0.23% (weight) in water and is insoluble in glycerol. But it can be miscible with alcohols, ethers, ketones, fatty hydrocarbons, aromatic hydrocarbons, etc. It has good dissolving ability to grease, nitrocellulose, cellulose acetate, etc., and can also dissolve rosin, triglyceride, coumarone resin, etc. Therefore, it is used as a solvent for shellac paint, alkyd resin, cellulose nitrate, cellulose acetate, dye, grease, printing ink, etc. Ester synthetic spices. Mainly used as a blend of jasmine, white orchid, hosta, yuxiaxiaxiang and other flavors. Because of the promotion effect on the fragrance of floral and fantasy flavors, and the low price, it has a wide range of applications in a variety of flavors. spices, solvents, oil, nitrocellulose and cellulose acetate, etc. have good dissolving ability, can also dissolve rosin, triglyceride and coumarone resin. Therefore, it is used as a solvent for shellac paint, alkyd resin, cellulose nitrate, cellulose acetate, dye, grease, printing ink, etc. |
| production method | 1. benzyl alcohol and acetic acid are used as raw materials, directly esterified under sulfuric acid catalysis to generate benzyl acetate, and then neutralized, washed and fractionated to obtain the finished product. 2. Benzyl chloride and sodium acetate are used as raw materials to react in the presence of catalyst pyridine and dimethylaniline to form benzyl acetate. The finished product is washed and distilled. benzyl acetate naturally exists in ylang oil, neroli oil, hyacinth oil, tuberose oil and gardenia oil. the industrial production is generally prepared by the following methods. Under the catalysis of sulfuric acid, benzyl alcohol and glacial acetic acid are mixed and heated for esterification. After the reaction is over, it is first neutralized with alkali, and then washed with water until neutral. After drying with anhydrous calcium chloride, the product is distilled under reduced pressure. A small amount of boric acid is added before distillation to make the excess benzyl alcohol and its action to form a high boiling point benzyl borate to stay in the distillation kettle. CH3COOH + C6H5CH2OH[H2SO4]→ CH3CHOOCH2C6H5 + H2O is prepared by reacting benzyl chloride with sodium acetate, and the chlorine in the product must be eliminated. The yield of this method can reach 80%. CH3COONa + C6H5CH2ClCH3COOCH2C6H5 + NaCl successively add 1kg of benzyl alcohol and 2kg of anhydrous sodium acetate to 1.2kg of acetic anhydride, slowly heat to 100 ℃, add 40g of anhydrous sodium acetate after the reaction is mild, and then reflow for 8h. After cooling, wash with water, neutralize with 10% NaOH solution, wash with water to neutral, and finally dry with anhydrous calcium chloride, and distill the product under reduced pressure. (CH3CO)2 + C6H5CH2OH[NaAc]→ C3H7COOCH2C6H5 + CH3COOH is made by heating and esterification of benzyl chloride and sodium acetate under pyridine catalysis, and then purified by distillation. It is made by esterification of benzyl alcohol with acetic anhydride or acetic acid and purified by distillation. |
