Abstract
The invention discloses a synthetic method of dibutyl ether. The synthetic method comprises following steps: n-butyl alcohol and concentrated sulfuric acid are delivered into a reactor provided with a reflux unit at a certain ratio; an obtained mixture is heated to 120 to 140 DEG C in the presence of a catalyst, and is subjected to full reaction for 1.5h; a reaction residue is cooled, water with a same volume is added, oil phase is removed, water phase is heated for evaporation dewatering, temperature is increased to 200 DEG C further, and steam is collected and is subjected to condensation so as to obtain a dibutyl ether crude product; and the dibutyl ether crude product is washed with saturated sodium chloride solution for 2 to 4 times so as to obtain a dibutyl ether refined product. The process of the synthetic method is easy to control; purity of the obtained dibutyl ether refined product is high; the production technology is compact; and byproducts are few.
Description
Technical field
The present invention relates to a kind of industrial chemicals synthetic method, be specifically related to a kind of synthetic method of dibutyl ether.
Background technology
Dibutyl ether has very strong solvency power to many natural and Synthetic Oil, resin, rubber, organic acid acetic, alkaloid etc., toxicity and danger little, be the very high solvent of security, the mixing solutions of the extraction and refining solvent and butyl phosphate that are widely used as resin, grease, organic acid, ester, wax, alkaloid, hormone etc. can be used as the solvent of separation of rare earth elements.Simultaneously because butyl ether is inert solvent, also can be used as the organic synthesis solvent of Grignard reagent, rubber, agricultural chemicals etc.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of synthetic method of new dibutyl ether.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of synthetic method of dibutyl ether, be characterized in: propyl carbinol and the vitriol oil are put in the reactor with reflux according to certain formula rate, under the effect of catalyzer, be heated to 120-140 DEG C, abundant reaction 1.5 hours, reaction residual is cooled, add isopyknic water, remove oil phase, by heated aqueous dehydration by evaporation, temperature is brought up to 200 DEG C further, vapor collection condensation is dibutyl ether crude product, then dibutyl ether saturated sodium chloride solution washing is dibutyl ether fine work for 2-4 time.
Compared with prior art, process of the present invention is easy to control, and product dibutyl ether purity is high, and meanwhile, whole production technique is compact, and byproduct is few.
Embodiment
Below further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
Embodiment 1, a kind of synthetic method of dibutyl ether, propyl carbinol and the vitriol oil are put in the reactor with reflux according to the formula rate of volume ratio 2: 1, under the effect of catalyzer, be heated to 140 DEG C, abundant reaction 1.5 hours, reaction residual is cooled, add isopyknic water, remove oil phase, by heated aqueous to 100 DEG C dehydration by evaporation, temperature is brought up to 200 DEG C further, vapor collection condensation is dibutyl ether crude product, then dibutyl ether is washed 4 times with saturated sodium chloride solution and be dibutyl ether fine work.
