The invention relates to lubricant compositions comprising (a) one or more mineral oils or synthetic oils and (b) 0.05 to 5% by weight of at least one compound of formulae I, II and III ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are as defined in claim 1; and (c) further optional lubricant additives. Some of these compounds are new and can be prepared by Mannich reaction from the appropriate 2-mercaptobenzothiazoles, an aldehyde R.sup.2 --CHO and a primary or secondary mono- or diamine. These Mannich bases are useful additives for lubricants for reducing friction, wear, corrosion and oxidation.
本发明涉及润滑剂组合物,包括(a)一种或多种矿物油或合成油和(b)0.05至5重量%的至少一种I,II和III式化合物##STR1##其中R.sup.1,R.sup.2,R.sup.3,R.sup.4和R.sup.5如权利要求1所定义;以及(c)进一步可选的润滑剂添加剂。其中一些化合物是新的,并且可以通过Mannich反应从适当的2-巯基苯并噻唑,醛R.sup.2-CHO和一种主要或次要单胺或二胺制备而成。这些Mannich碱是有用的润滑剂添加剂,可用于减少摩擦、磨损、腐蚀和氧化。
