摘 要: 本論文簡(jiǎn)述了粗羊毛脂精制的必要性 ,并介紹了國(guó)內(nèi)外羊毛脂精制的工藝方法及其新進(jìn)展。通過(guò)添加四元精練劑來(lái)優(yōu)化酸化、精煉、沉降、脫色、洗滌、脫水等工藝條件，可生產(chǎn)優(yōu)質(zhì)的羊毛脂制品。本工藝與傳統(tǒng)工藝相比具有純度高、成本低、生產(chǎn)工藝簡(jiǎn)單等優(yōu)點(diǎn)，其下腳料可進(jìn)一步用來(lái)生產(chǎn)二價(jià)羊毛酸鹽，廣泛用于金屬防銹、潤(rùn)滑等行業(yè)。從而解決了下腳料污染環(huán)境的問(wèn)題。通過(guò)實(shí)驗(yàn)得出的最佳反應(yīng)條件為：四元精制劑（Na5P3O10:Na2SO4:NaOH:H2O）的最佳配比為6:6:3:85,精煉的溫度為90℃，沉降促進(jìn)劑選用異丙醇，在60℃下用雙氧水脫色6小時(shí)。通過(guò)本工藝條件來(lái)精制出的羊毛脂產(chǎn)率可達(dá)到85%，且色澤較好。

Abstract: Necessity of crude lanolin refinement was expressed simplely, and the processing method and the new development of lanolin refinement both at home and abroad are introduced. By using a quadplex–component refining agent, through acidification, refining, settlement, crocking, washing and dehydration, high-quality lanolin will be produced. Comparing to the traditional method of refining wool fat ,using this method, the purity of lanolin is higher, the cost is lower and the operation is more convenient .The waste product of this method can be used to produce diatomic lanolin salt which can be used in rust-proof and lubrication, therefore, the problem of polluting is resolved. Through the experiment, the result enunciate that the most suitable and proper reaction conditions is that: the proportion of quadplex–component (Na5P3O10: Na2SO4: NaOH: H2O) is 6:6:3:85, the temperature of refining is 90℃ ,the choice of settlement solvent is Isopropanol, at 60 ℃ under six hours with hydrogen peroxide decolorization. Through the refining process to yield to lanolin can reach 85% and the colour is better.
