摘要： A process for making substantially odorless granules of alkyl sulfates corresponding to formula (I): R-O-SO3X (I) wherein R is an alkyl group containing from 6 to 18 carbon atoms, and X is selected from the group consisting of an alkali metal, an alkaline earth metal, ammonium, an alkyl ammonium, and alkanolammonium, and a glucammonium ion, the process involving: (a) providing a water-containing paste of alkyl sulfates having a content of unsulfonated components of greater than 0.3% by weight; and (b) simultaneously granulating and drying, in a fluidized bed, the water-containing paste of alkyl sulfates to form substantially odorless granules of alkyl sulfates, and wherein the substantially odorles granules thus formed have less than 0.2% by weight, based on the weight of active substance, of unsulfonated components present therein.
摘要翻译：对应于式（I）的基本无臭的烷基硫酸盐颗粒的方法：RO-SO 3 X（I）其中R是含有6至18个碳原子的烷基，X选自碱金属，碱土金属，铵，烷基铵和链烷醇铵和葡萄糖铵离子，所述方法包括：（a）提供含有大于0.3重量％的未磺化组分含量的烷基硫酸盐的含水浆料; 和（b）在流化床中同时造粒和干燥烷基硫酸盐的含水浆料，以形成基本上无气味的烷基硫酸盐颗粒，并且其中由此形成的基本上气味的颗粒的含量小于0.2重量％，基于活性物质，其中存在的未磺化组分的重量。
