A sperm oil substitute, having extreme pressure and anti-wear properties consisting of a lubrication composition comprising a major amount of a lubrication oil and a minor amount of an extreme pressure and anti-wear additive, comprising (I) a diester of the condensation product of (A) a dicarboxylic acid or a dicarboxylic acid anhydride, and (B) a linear unsaturated alcohol; and optionally, in combination with, (II) a linear unsaturated alcohol, wherein from about 6 weight percent to about 20 weight percent of said combined diester and linear alcohol comprising the sulfide moiety.

Extreme pressure lubricating compositions

A process for the simultaneous production and purification of 4-nitro-o-phthalic anhydride which comprises subjecting an impure mixture containing 4-nitro-o-phthalic acid to azeotropic dehydration with selected azeotroping agents.

Simultaneous production and purification of 4-nitro-omicron-phthalic

A process for converting (1) an indene, (2) a polyindene, (3) a dihydronaphthalene or (4) a polydihydronaphthalene to 4-nitro-o-phthalic acid which involves nitrating said indene, polyindene, dihydronaphthalene or polydihydronaphthalene and then oxidizing said nitrated indene, polyindene, dihydronaphthalene or polydihydronaphthalene with nitric acid.

Process for preparing 4-nitro-o-phthalic acid

A process for producing maleic anhydride from a hydrocarbon mixture containing C.sub.5 monoolefinic hydrocarbons, C.sub.5 diolefinic hydrocarbons, (cyclic and acylic) C.sub.5 paraffins, C.sub.6 paraffins and benzene which involves separating the C.sub.5 cyclic diolefinic hydrocarbons from the mixture and then reacting the resulting mixture with molecular oxygen in vapor phase in the presence of an oxidation catalyst at elevated temperatures.

Process for producing maleic anhydride from mixture of five and six

The present invention relates to a process for inhibiting the polymerization of styrene monomers during the purification of crude styrene.

Process for inhibiting the polymerization of styrene

A novel and efficient oxidation process for preparing quinone alkides from the corresponding tri-alkyl or phenyl hindered phenols, utilizing ferricyanide as the secondary oxidant in combination with persulfate as the primary oxidant.

Quinone alkide synthesis system

The present invention relates to the use of quinone alkides as polymerization inhibitors in a styrene purification process. The inhibitors are prepared by oxidizing hindered phenols to the corresponding quinone alkide.

Styrene purification process

A process for converting styrene bottoms to nitrobenzoic acids, particularly para-nitrobenzoic acid, which involves nitrating styrene bottoms and then oxidizng the nitrated styrene bottoms.
