专利号:US-5110950-A 优先权日:1991-06-12 标题 :Method of preparing 2-phosphorylated compounds of ascorbic acid 发明人:SEIB PAUL A; WANG XIAO Y 权利人:UNIV KANSAS STATE 摘要:A catalyzed synthesis of ascorbate 2-phosphorylated compounds is provided which gives both mono-and polyphosphorylated species in excellent yield using inexpensive, readily available reactants. The method involves forming a reaction mixture of an ascorbic acid reactant such as L-ascorbic acid and a metaphosphate phosphorylating agent (e.g., sodium trimetaphosphate), and carrying out the phosphorylation reaction in the presence of a catalyzing ion selected from the group consisiting of calcium, strontium and barium ion and mixtures thereof, while maintaining the pH of the reaction mixture at a level of from about 3-12. The synthesis is characterized by very short reaction times, preferably from about 15 minutes-2 hours, and moderate temperatures on the order of 18 DEG C.-25 DEG C. Preferably, the catalyzing ion is provided by addition of calcium, strontium or barium hydroxide to the reaction mixture, this serving to also elevate the pH of the system to the desired range.

专利号:WO-2025103764-A1 优先权日:2023-11-14 标 题 :Alkoxylated polymer and synthesis thereof with reduced dioxane formation 发明人:HUEFFER STEPHAN; ETTL ROLAND; GARCIA MARCOS ALEJANDRA 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.
