摘要:
A lubricating oil composition for railway diesel engines is disclosed which comprises a lubricating oil base, an ashless dispersant, a mixture of overbased alkaline earth metal alkylphenolate and alkyl sulfonate compounds, and a polyhydroxy compound of up to 60 carbon atoms or a mixture of a polyhydroxy compound of up to 60 carbon atoms and a chlorinated hydrocarbon.
摘要:
Long chain (4-hydroxyphenyl) propanoate derivatives of the formula ##STR1## are effective in stabilizing organic materials against oxidative and thermal degradation.
摘要:
Lubricating oil compositions are disclosed exhibiting improved fuel economy which contain 0.05 to 0.2 wt. % of a glycerol partial ester of a C.sub.16 -C.sub.18 fatty acid as the fuel economy additive.
摘要:
A refrigerator oil composition is described, comprising: (1) at least one of mineral oil and synthetic oil and (2) at least one of (a) 15-crown-5, (b) a derivative of 15-crown-5, and (c) a glycidyl compound represented by the general formula: ##STR1## (wherein R is hydrogen or an alkyl group containing from 1 to 5 carbon atoms). This composition exhibits high stability when in contact with halogen-containing refrigerants and is limited in the formation of hydrogen chloride, for example, resulting from its reaction with the halogen-containing refrigerants. Thus the refrigerator oil composition of the invention is useful as a lubricant for refrigerators.
摘要:
Novel dicarboxylic ester-acids resulting from the condensation of an alkenylsuccinic anhydride with an aliphatic hydroxy acid having from 2 to about 18 carbon atoms and amine salts of said ester-acid are useful as rust or corrosion inhibitors in organic compositions.
摘要:
