Description
Technical field
The present invention relates to a kind of biological processing field, the particularly biological plasticising of kitchen castoff oil and fat preparationThe method of agent epoxy aliphatic acid methyl ester.
Background technology
In the process of city, rubbish was once the burden of urban development as the product of metabolism, and the world is manyAll there is the situation of garbage-surrounded city in city. It is tool potentiality to be exploited, never withered exhausted that now rubbish is considered to" city mineral reserve " are " resources that misplaces ground ", and this is going deep into and in-depth that rubbish is familiar with, is also that city is sent outExhibition inevitable requirement.
House refuse refers to the various discarded objects that dumped by resident in municipal refuse, refer in daily life orPerson looks for daily life provides the solid waste that produces in the activity of service and law, administrative regulation regulationFor the solid waste of house refuse. Be divided into four classes: recyclable rubbish, rubbish from cooking, Harmful Waste and itsIts rubbish. Recyclable rubbish comprises stationery, metal, plastics, glass etc.; Rubbish from cooking and market rubbishThe food such as internal organ that comprises the rotten food of surplus tea leftovers, bone, dish root, dish leaf, chicken, duck, fish is uselessThing; Harmful Waste comprise battery, useless fluorescent lamp, useless mercurial thermometer, expired medicine etc.; Other rubbishThat brick and tile pottery except above-mentioned a few class rubbish, dregs, toilet waste paper etc. are difficult to recyclingDiscarded object.
Whole world rubbish average speed of growth is 8.42%, and Chinese rubbish growth rate reaches 10%, full generation4.9 hundred million tons of rubbish of the annual generation in boundary, only China just produces nearly 1.5 hundred million tons of municipal refuses, its Chinese meal kitchen every yearRubbish accounts for 30～40% of domestic waste, and wherein very most of be kitchen castoff grease. InOneself reaches 7,000,000,000 tons state's domestic waste accumulation amount of piling. Under so huge rubbish pressure, have reasonBelieve that garbage disposal generation can become following domestic star's industry.
Along with the development of national economy, garbage disposal handling, on the agenda of governments at all levels, passesIt is high that the garbage disposal of system has operating cost, and output is little, and landfill is completely without problems such as outputs, even governmentInvestment construction, annual great number operating cost also can become the great burden of local government. The current rubbish of ChinaThe processing method landfill of rubbish and burning are Main Means, and garbage loading embeading need to occupy a large amount of soils, in cityCity and industrialized epoch, being in an emergency of land resource, this road is not shortcut yet, and easily producesSecondary pollution, waste precious resources.
Plasticizer accounts for 58% of auxiliary chemicals market, its specific product comprise phthalic acid ester (DOP),Fatty group dibasic acid, phosphate epoxide, trimellitate, petroleum ester, chloro-plasticizer,Polymeric plasticiser etc. At present consumption figure is very large plasticizer year, along with the development of plastics, rubber industry, cityField demand is in rising trend. Above-mentioned plasticizer contains phenyl ring mostly, and poisonous and difficult degraded, makesWith or production process in, can work the mischief to environment and health, the scope of application is restricted. So far nothing,Poison environment-friendly type plasticizer is also little, and proportion less than 10%, is mainly epoxy plasticiser, as epoxyOil and epoxy-ester. At present also have relevant document and report, as utilize soybean oil, linseed oil, cottonseed oil,Rape seed oil, rice bran wet goods are raw material, obtain the epoxy plasticizer of non-toxic degradable through epoxidation; Also favourableWith fatty acid ester be raw material, under the effect of catalyst and stabilizing agent, carry out epoxidation prepare epoxy increaseMould agent. But they have following shortcoming: 1., taking vegetable oil as raw material, production cost is higher; 2. epoxidation mistakeCheng Zhong, adds acidic catalyst and stabilizing agent, and the epoxide number of product reduces, and affects the plasticization effect of product,And complex manufacturing, post processing difficulty.
Therefore, the method for the biological plasticizer epoxy aliphatic acid methyl ester of a kind of kitchen castoff oil and fat preparation is providedThere is realistic meaning.
