甘脲,乙酸酐置于磷酸体系中,化学反应 0.5H,以98%的收率获得四乙酰甘脲

标题:含磷催化剂有效合成四乙酰基甘脲
摘要:摘要 含磷催化剂,即亚磷酸,磷酸,亚乙基二亚磷酸氢盐和1-羟基乙烷-1,1-二基二膦酸(hedp)在140oc下通过将甘醇脲与乙酸酐酰化合成四乙酰基甘脲醇中的作用已经研究过了.已发现相对于甘脲,使用4当量的亚磷酸或磷酸是最适合获得最大收率(95-98%)的方法,Hedp的特殊作用会导致底物的n-乙酰化-脱乙酰化.磷酸对四乙酰基甘脲的形成的积极影响可能不仅与它们的催化作用有关,而且与溶解底物的能力有关.

权利人:BASF SE
摘要:The present application relates to an alkoxylated polymer consisting of (i) triethanolamine (TEA) and/or triisopropanolamine (TIPA) units and (ii) chains of alkylene oxide units, where the components are chosen so as to give rise to a biodegradable polymer with washing power that can be synthesized with reduced dioxane formation. The application is also directed to a cleaning composition comprising the alkoxylated polymer, to the use of the inventive polymer for boosting the primary washing power of washing compositions, to a cleaning method and to the use of (i) triethanolamine (TEA) and/or triisopropanolamine, (ii) ethylene oxide (EO) and (iii) propylene oxide (PO) for low-dioxane production of an alkoxylated polymer.
