Description
Technical field
The utility model relates to a kind of liquid-phase reaction system for the synthesis of the polymethoxy dialkyl ether, mainly is applicable to the technical process of synthetic polymethoxy dialkyl ether (DMMn); Also can carry out using in still reaction at other liquid-liquid phase, gas and liquid phase, solid-liquid phase compound, be expected to be widely used (comprise the fields such as medicine intermediate, agricultural chemicals, biochemical industry, catalyst, various additive, auxiliary agent, coating, dyestuff, reagent, oil field chemical, electronics and Photochemicals) in fine chemistry industry and specialty chemicals industry in.
Background technology
The imbalance between supply and demand of China's diesel oil is always very sharp-pointed, and the one, supply quantity can not satisfy quick, the sustainable growth of China market demand; The 2nd, diesel quality is relatively poor, and its Cetane number setting that usually is difficult to be up to state standards is 45 requirement.Diesel car exhaust has become one of the main sources of urban air pollution.June 12 in 2012 is the IARC of the World Health Organization (WHO) (IARC) bulletin everyday, this mechanism determines to promote the carcinogenic hazard rating of diesel motor tail gas, rises to " determining carcinogenic " classification by " may the be carcinogenic " classification that incorporated in 1988.This important decision has proposed higher, more urgent requirement to the quality requirement of diesel oil.
DMMn is the best diesel cetane-number improver of generally acknowledging both at home and abroad, in 10% ~ 20% ratio with the blending of DMMn and diesel component after, can improve the finished diesel fuel oxygen content, can improve the efficiency of combustion of diesel oil, and significantly reduce the discharging of the diesel combustion pollutants such as carcinogenic substance, NOx and CO.Because polymethoxy dialkyl ether Cetane number is up to 75, its physical property is similar to diesel oil, does not need the engine fuel system of In-Use Motor Vehicles is made any change so be blended into to use in diesel oil.Add all characteristics that this class material can improve diesel oil in ordinary diesel oil, not only Cetane number significantly improves, and its cryogenic property also can improve.In addition, because diesel oil is diluted, its contained carcinogenic aromatic compound and the content of sulphur and their density have all reduced.According to measuring and calculating, my Country every year is about 2,500 ten thousand tons to the requirement of polymethoxy dialkyl ether, and its research, exploitation of carrying out technology is had important practical significance undoubtedly.
