摘 要:油脂化工产品的原料来自于动物性和植物性的油和脂肪 ,它们也衍生许多化工产品。然而 ,由于油脂化工产品的独特性质 ,它主要为肥皂、清洁剂和洗发水等产品提供广泛的表面活性剂原料。通常在制成品前 ,这些基本的油脂化工产品需进行进一步的转化程序。油脂化学品原料取之天然可再生 ,可生物降解 ,而石油原料却无法再生。因此 ,从这一点来讲油脂化学品对环境更友好。指出油和脂肪的价格变化无常 。The raw materials for oleochemicals are animal and plant origin oils and fats.Many derivatives are made from these chemicals but the primary end-uses are in soap,detergents,shampoos etc.where the unique properties of oleochemicals provide the basis for a wide range of surfactant materials.In most instances a further conversion of the basic oleochemical to a derivative is needed before inclusion the end products.One important aspect of oleochemicals,whether derived from natural materials or petroleum is that they are all biodegradable.The only real difference in environmental friendliness is that nature based oleochemical raw materials are renewable whilst petroleum based materials are not.The economics of oleochemical production is highly erratic,the two major variables the price of oils and fats and the value of co-product glycerin vary widely on a supply/demand basis.
