Abstract

The invention discloses a dimethyl-carbonate-containing composition and a preparation method and application thereof. The dimethyl-carbonate-containing composition comprises the following components in percentage by weight: 40 to 86.8 percent of dimethyl carbonate, 3 to 15 percent of alkyl nitrate, 5 to 20 percent of alcohol of which the number of carbon atom is less than 6, 0.2 to 5 percent of ash-free dispersing agent and 5 to 20 percent of hydrotropy agent. The method for preparing the dimethyl-carbonate-containing composition comprises the following steps of: adding the dimethyl carbonate into a reaction kettle; adding the alkyl nitrate, the alcohol of which the number of carbon atom is less than 6, the ash-free dispersing agent and the hydrotropy agent while stirring; and dissolving completely to obtain finished products. The dimethyl carbonate-containing composition can serve as a three-way catalytic converter cleaning agent, and all-round cleaning of the whole automobile engine system is realized.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a composition containing dimethyl carbonate, a preparation method and application thereof. Background technique [0002] Due to the poor quality of fuel supplied in China and the widespread use of manganese-containing anti-riot agents in fuel, the use of ethanol gasoline and methanol gasoline has been promoted in some areas in recent years. Due to factors such as sulfur and phosphorus additives added to gasoline engine oil, and roads that are not smooth, the oxygen sensor, the three-way catalytic converter will be poisoned or blocked, and the throttle valve, intake manifold, and combustion chamber will be damaged after a certain mileage. Colloidal carbon deposits are deposited, affecting the normal operation of the engine, causing problems such as increased fuel consumption, reduced power, and excessive exhaust gas. Need a kind of simple and effective treatment technology measure. ...
