Problems solved by technology

According to the manual, it solves the problem of poor compatibility between methanol and gasoline, and has good cold start performance, but it cannot be mixed with other types of gasoline, and it is prone to oil circuit blockage
In addition, according to its technical characteristics, the amount of methanol added is small, and the economic benefits are not obvious. At the same time, ether compounds cannot completely solve the problem of poor compatibility of methanol gasoline, otherwise, there will be no problem that it cannot be mixed with other gasoline. Secondly, methanol gasoline formulated with such additives is prone to clogging of oil passages and is difficult to promote to market users.

Embodiment 1

[0030] Prepare 49.5kg of methyl formate, 15kg of cosolvent isopropyl ether, 34kg of combustion enhancer isoheptanol; 0.5kg of ethanolamine; 1kg of benzotriazole. The preparation process is as follows: first put methyl formate in the batching tank, then add isopropyl ether and isoheptanol, and then add ethanolamine and benzotriazole while stirring. Self-circulation four times, stand still for 40 minutes, obtain the additive of alcohol ether fuel.

[0031] This kind of additive has excellent solubilizing ability and can effectively reduce fuel consumption.

Embodiment 2

[0033] Prepare 30kg of trimethyl phosphite, 40kg of n-propyl ether, 25kg of isoheptanol; 4.5kg of triethylamine; 0.5kg of benzotriazole. The preparation process is as follows: first put n-propyl ether in the batching tank, then add isoheptanol, add triethylamine under stirring, and finally add trimethyl phosphite and benzotriazole. Self-circulation four times, stand still for 40 minutes, obtain the additive of alcohol ether fuel.

[0034] This kind of additive can effectively inhibit corrosion and reduce oil circuit blockage.

Embodiment 3

[0036] Prepare 10kg of diethyl carbonate, 34.6kg of dimethyl ether, 50kg of isobutanol, 5kg of diethanolamine, and 0.4kg of benzotriazole. The preparation process is as follows: first put diethyl carbonate in the batching tank, then add dimethyl ether, add isobutanol while stirring, and finally add diethanolamine and benzotriazole. Self-circulation four times, stand still for 40 minutes, obtain the additive of alcohol ether fuel.

[0037] This kind of additive has good cold start performance.

The addition agent comprises methyl formate, methyl methacrylate, trimethyl phosphate, dimethyl carbonate or 10-50wt% diethyl carbonate, dimethyl ether, isopropyl ether, propyl ether, 15-40wt% ethyl ether, isoamyl alcohol, isobutyl alcohol or 15-50wt% isoheptyl alcohol, aminoethyl alcohol, diethyl ethanolamine, triethylamine, hexadecylamine, octadecyl ammonium, 0.5-5wt% nitroaniline, and 0.1-1wt% nufenoxole. The invention has the advantages of non emulsification, non three wastes, low energy consumption and high productivity.

Description

technical field [0001] The invention relates to the field of alcohol ether fuel additives. Background technique [0002] With the economic development of our country, the automobile industry has entered a period of rapid development. In 2002, the number of automobiles in my country was 20 million. It is estimated that the potential number of automobiles in 2020 will exceed 150 million. As a result of the sharp increase in vehicles, the demand for refined oil has increased rapidly. The continuous increase of oil demand will seriously affect the healthy development of national economy and the security of energy and economy. At the same time, the exhaust gas emitted by automobiles has greatly polluted the living environment of human beings, threatening people's health and lives. Coping with the oil crisis, improving the security of fuel supply, preparing for the smooth transition of fuel types after the depletion of oil resources, improving the efficiency of existing energy a...
