Method for processing wastes generated during butyl butyryl lactate production process

Abstract

The invention discloses a method for processing wastes generated during the butyl butyryllactate production process, and relates to the technical field of essence preparation. The front fraction and the rear fraction are individually processed so as to obtain finished products and corresponding raw materials, and then a secondary treatment is carried out. A large amount of wastes generated during the butyl butyryl lactate production process is processed, moreover an isoamyl acetate product is obtained, at the same time butyl lactate and butyric anhydride are extracted from the wastes and used to carry out secondary reactions to prepare butyl butyryl lactate, the wastes are fully utilized and converted into valuable resources, the resource comprehensive utilization rate is improved, furthermore the treatment is simple, and the method is reasonable.

Description

technical field [0001] The invention relates to the technical field of perfume preparation, in particular to a method for treating waste generated in the production of butyl butyryl lactate. Background technique [0002] Fragrances are concentrated aromatic oils that are artificially imitated by the smell of fruits and natural spices. It is mostly used in the manufacture of food, cosmetics and cigarettes, etc. Edible flavor refers to the fragrance of natural food, using natural and natural equivalent spices and synthetic spices to carefully blend various flavors with natural flavors. Including fruit water quality and oil quality, milk, poultry, meat, vegetables, nuts, candied fruit, emulsification and wine and other flavors, suitable for beverages, biscuits, pastries, frozen foods, candies, seasonings Butyryl lactate is a colorless liquid in food, dairy products, canned food, wine and other foods, which has a soft aroma of butter and toast.

Problems solved by technology

Flash point 100°C, 1ml sample is dissolved in 3mL of 70% ethanol, soluble in propylene glycol and most non-volatile oils, hardly soluble in water and glycerin, equal to natural fragrance and artificial fragrance, so it is a commonly used fragrance in the market, however During the preparation of butyl butyryl lactate, a large amount of waste will be produced. The direct discharge of these wastes will not only cause environmental pollution, but also a large amount of butyric acid, butyl lactate and butyl butyryl lactate contained in the waste It is also directly discharged, which is more wasteful
