用途广泛的平台化合物——双乙烯酮

A Platform chemical compound of multpurpose——diketene

介绍了双乙烯酮在国内外的生产情况,并对它或以它的衍生物作原料,在医药、农药、染料、有机合成等方面的应用作了较详细论述。目前国内双乙烯酮的生产能力较大,预计2007年其总产量将达120 kt/a,而目前我国的年需求量只有55～60 kt。所以,在国内再新、扩建双乙烯酮的企业应该持谨慎态度和充分考虑国内的市场状况。以双乙烯酮或相关的衍生物作原料,可开发的下游化工产品多达400多种。所以,开发其中一些有价值的新农药、尤其是医药及其中间体将具有广阔的市场前景,同时也是消化双乙烯酮的唯一好途径。

Diketene had several special physical - Chemical properties and its synthetic method were introduced. Which have high reactivity for its high unsaturation, so that it application in many ways, such as：pesticide, medicine, dyestuff and food additive,etc, was summarized in detail. At present, forecasted the total capacity of Diketene is about 120 k/a, with total consumption about 50 ～60 kt in 2007 ,Supple and demand of Diketene differs to certain extent in China. Therefore strongly develop downstream products of diketene would be a well prospect. If a new set is needed to be bulit, should be comprehensively considered in markect demand at home.
