A higher secondary alcohol alkoxylate compound composition represented by the general formula (1):
[wherein R1 and R2 represent an alkyl group provided that the total number of carbon atoms of R1 and R2 is in the range of 7 to 29 and the number of carbon atom of R2 is not less than that of R1 (the number of carbon atom of R1 ≤ the number of carbon atom of R2), A represents a lower alkylene group, n represents a numeral in the range of 1 to 50 on the average; providing that when n is not less than 2, the number of species of oxyalkylene group represented by AO may be either one or two or more, and that when the oxyalkyl groups have two or more species, all the oxyalkylene groups are present in the average of n, and B represents a hydrogen atom or SO3M (wherein M represents an alkali metal atom, an alkaline earth metal atom, an ammonium group or a substituted ammonium group)], wherein the composition comprises 30 to 90 mol% of the higher secondary alcohol alkoxylate compound (X) having a methyl group for R1 and 70 to 10 mol% of the higher secondary alcohol alkoxylate compound (Y) having an alkyl group of 2 or more carbon atoms for R1, a method for the production thereof, and a detergent and an emulsifier using the composition.
一种由通式(1)表示的高级仲醇烷氧基化合物组合物:
[其中 R1 和 R2 代表烷基,条件是 R1 和 R2 的碳原子总数在 7 至 29 之间,且 R2 的碳原子数不少于 R1 的碳原子数(R1 的碳原子数≤R2 的碳原子数),A 代表低级亚烷基,n 代表平均在 1 至 50 之间的数字;规定当 n 不小于 2 时,AO 所代表的氧亚烷基的种类数可以是一个或两个或更多,当氧亚烷基有两个或更多种类时,所有氧亚烷基都存在于 n 的平均值中,B 代表氢原子或 SO3M(其中 M 代表碱金属原子、碱土金属原子、其中 M 代表碱金属原子、碱土金属原子、铵基团或取代的铵基团)],其中该组合物包括 30 至 90 摩尔%的 R1 为甲基的高级仲醇烷氧基化合物(X)和 70 至 10 摩尔%的 R1 为 2 个或更多碳原子的烷基的高级仲醇烷氧基化合物(Y)、其生产方法以及使用该组合物的洗涤剂和乳化剂。
