The objectionable odors generated from lubricants is minimized by including in said lubricant a thiazole compound and grape odor mask.

Elimination of odors from lubricants by use of a combination of thiazoles and odor masks

Polyalkylene substituted carboxylic acylating agents which contain chlorine are synthesized by chlorine induced condensation of polyalkylenes and .alpha.-.beta. unsaturated carboxylic groups are treated with sulfur to reduce chlorine content of the carboxylic acylating agent.

Low chlorine polyalkylene substituted carboxylic acylating agent

An additive composition of (a) a substituted aromatic triazole and (b) a hydrocarbyl substituted succinic acylated polyamine dispersant, reacted with a boron compound, imparts improved corrosion resistance to lubricating oils which contain a multifunctional olefin copolymer viscosity index modifier.

Lubricant with improved anti-corrosion properties

Combinations of substituted carboxylic (especially succinic) acid esters and heterocyclic condensation products of said substituted carboxylic acids are useful in lubricants for inhibitors of 'lead paint' deposition in internal combustion engines. Especially useful are compositions comprising a major proportion of a pentaerythritol ester of an alkenyl succinic acid in which the alkenyl group contains at least about 30 carbon atoms, and a minor proportion of a heterocyclic condensation product of said alkenyl succinic acid derived from a 5-membered ring heterocycle containing at least two ring hetero atoms separated by a single carbon atom, at least one of said hetero atoms being nitrogen.

Ester-heterocycle compositions useful as 'lead paint' inhibitors in

The present invention is directed to a class of novel 1-benzoyl-3-thiosemicarbazides which are useful as plant growth regulants. The present invention is also directed to methods and formulations for plant growth regulation.

Substituted thiosemicarbazides, their manufacture and use as plant

A method of regulating the growth of plants, including combating unwanted vegetation, comprises applying to the plants, either on seed, the soil or directly on the plants an effective amount of a novel compound of the class having the general structural formula ##STR1## in which one of Q.sub.1, Q.sub.2, Q.sub.3 or Q.sub.4 is N, X is --OH or --O--(C.sub.1 -C.sub.4 alkyl) and Y is H or X and Y together represent a bond between carbon and nitrogen atoms and R is H or one or two of the following substituents: --Br, --Cl, --F, --I, --CF.sub.3, --CH.sub.3, --NO.sub.2 or --C.tbd.N, or an agriculturally acceptable salt thereof.
