    • Disclosed are pumpable surfactant compositions of alkanolamine salts of alkyl phosphate esters. The compositions have a solids content of about 60% by weight or more. Alkanolamines useful in preparation of the alkyl phosphate ester salts of the compositions of the present invention have the following formula III: wherein R4 to R6 are, individually, hydrogen or C1-8, linear or branched alkyl, alkenyl, alkaryl or aralkyl hydrocarbon moieties, which optionally may contain carbocyclic rings. At least one of the amine substituents is different from the other two. For at least one of the three substituents on the amine nitrogen, the sum of s and t (s+t) or v and w (v+w) or x and y (x+y) is equal to or greater than 1 and the corresponding R (R4, R5 or R6) is hydrogen. The subscripts p and q, individually, may be the same or different and are integers from 2 to 4. The subscripts s, t, v, w, x, and y, individually, may be the same or different and are integers of from 0 to 10, with the proviso that the sum of all six of the subscripts is less than or equal to 12.
    • 公开了磷酸烷基酯的链烷醇胺盐的可泵送表面活性剂组合物。 组合物的固体含量为约60重量%以上。 用于制备本发明组合物的烷基磷酸酯盐的烷醇胺具有下式III:其中R 4至R 6各自为氢或C 1-8直链或支链烷基,链烯基,烷芳基或芳烷基烃部分, 其任选地可以含有碳环。 至少一个胺取代基与另外两个不同。 对于胺氮中的三个取代基中的至少一个,s和t(s + t)或v和w(v + w)或x和y(x + y)之和等于或大于1, 相应的R(R4,R5或R6)是氢。 下标p和q各自可以相同或不同,为2至4的整数。下标s,t,v,w,x和y各自可以相同或不同,为 0至10,条件是所有六个下标的总和小于或等于12。
