More Information
Summary:The invention relates to the use of at least one compound having the following formula (I) as an anti-wear additive (anti-wear component) and as a friction modifier in lubricants, in which: R and R ', identical or different, are each an aliphatic group, preferably containing between 5 and 23 carbon atoms; and a and b are integers from 0 to 4; and A is a methylene-CH2-; or carbonyl-C (= O)-. # imgabs0 # 本发明涉及至少一种具有下式(I)的化合物作为润滑剂中的抗磨添加剂(抗磨组分)和摩擦改良剂的用途，其中：R和R'，相同或不同，各自是脂肪族基团，优选地含有在5个与23个之间的碳原子；并且a和b是从0至4的整数；并且A是亚甲基-CH2-；或羰基-C(＝O)-。#imgabs0#
