Carbinol gasoline additive and preparation method and application thereof

Abstract

The invention relates to glycerin ring acetal (ketal) ether used as a carbinol gasoline additive, and also relates to a preparation method of the glycerin ring acetal (ketal) ether and carbinol gasoline added with the carbinol gasoline additive. The glycerin ring acetal (ketal) ether consists of glycerin ring acetal (ketal) ether shown in a formula (I) and / or glycerin ring acetal (ketal) ether shown in a formula (II), wherein R1 is CnH2n, and n=1or 2 or 3; and R2 is CmH2m, m is an integer from 1 to 10. The invention contains the carbinol gasoline for combining the glycerin ring acetal (ketal) ether, thus the performance of low temperature cold boot is excellent, and the problem that air resistance can be generated when an automobile engine is filled with the carbinol gasoline under a high temperature environment can be solved.

Description

technical field The invention relates to a methanol gasoline additive, and also relates to a preparation method and application of the methanol gasoline additive. Background technique With the rapid development of the world economy, the number of cars is increasing year by year. At present, the number of cars in my country is more than 70 million. The demand for vehicle fuel is increasing, and environmental problems are becoming more and more serious. With the increasing shortage of energy reserves in the world, The situation of depletion of oil resources will become more severe. my country's economy is developing at a high speed, and most of the oil consumed every year needs to be imported. Energy and environmental issues restrict the rapid development of my country's economy. Therefore, seeking new clean alternative energy has become a key issue to promote my country's economic development. Gasoline has always been the main fuel for light vehicles, but this usage patter...
