Method for synthesizing methyl tert-butyl ether

Abstract

The invention provides a method for synthesizing methyl tert-butyl ether. The method comprises the following steps: 1) taking montmorillonite, soaking in deionized water for 25 minutes, removing impurities, drying in a drying oven for 2.5 hours, taking out the montmorillonite and performing crushing, and sieving; and (2) adding the sieved montmorillonite into an acetic acid solution with the mass fraction of 35%, stirring for 45 minutes at 75 DEG C by using a device for synthesizing methyl tert-butyl ether, then adding a titanate coupling agent and dicumyl peroxide, heating to a reflux state, carrying out heat preservation and stirring for 2 hours, filtering while the solution is hot, washing the solid by using deionized water and absolute ethyl alcohol to remove impurities, and performing vacuum drying at 50 DEG C to obtain a modified carrier. By arranging a first box body and a second box body, the first box body and the second box body are mounted in a matched manner, and the first box body and the second box body are convenient to mount and dismount, so that the interiors of the first box body and the second box body are convenient to clean.

Description

technical field [0001] The invention relates to the technical field of methyl tert-butyl ether preparation, in particular to a method for synthesizing methyl tert-butyl ether. Background technique [0002] Methyl tert-butyl ether (methyl tert-butyl ether, MTBE for short) is an organic compound with a chemical formula of C5H12O, a molecular weight of 88.15, an appearance of a colorless liquid, a relative density of 0.7405, and a boiling point of 55.2°C. It is soluble in ethanol , Ether, slightly soluble in water. Produced by the reaction of isobutylene and methanol under the catalysis of ion exchange resin, it is a high-octane gasoline additive. It is often used as a gasoline additive to improve the cold start characteristics, acceleration performance and octane number distribution of gasoline. In the existing technology, in the process of synthesizing methyl tert-butyl ether, stirring equipment is required. After the material is stirred and mixed, it is necessary to clean ...

Problems solved by technology

It is often used as a gasoline additive to improve the cold start characteristics, acceleration performance and octane number distribution of gasoline. In the existing technology, in the process of synthesizing methyl tert-butyl ether, stirring equipment is required. After the material is stirred and mixed, it is necessary to clean the inside of the mixing and mixing equipment to avoid affecting the next mixing and mixing. The existing mixing and mixing equipment is basically a whole and cannot be disassembled, which makes it inconvenient to clean the inside
