摘要:
Novel tetraalkyl phosphonium aluminosilicates can be produced by the ion exchange reaction of metal aluminosilicates with phosphonium salts. For example, layered type tetraalkyl phosphonium derivatives of clays are prepared by the reaction of sodium clays with tetraalkyl phosphonium chlorides. The novel compositions have unexpected microstructure, thermal stability, and thixotropic properties in organic liquids.

Improved deodorant formulations and antiperspirant formulations are secured by using as an ingredient thereof particular aliphatic diols and their esters.
摘要:
A process for the hydroconversion and hydrodenitrogenation of 1050*F.+ heavy crudes and residua. Hydroconversion of the 1050*F.+ materials is conducted in a first or initial reaction zone with a large pore catalyst to provide increased 1050*F.-or gas oil yield of high nitrogen content, and the product is treated in a subsequent reaction zone with an aluminum phosphate catalyst. The process combination provides overall increased gas oil yield of low nitrogen content.
摘要:
Novel interpolymers containing an olefin, a polar monomer, such as an alkyl acrylate, and from 0.05 to 35 mole % of a fumarate ester or a maleic acid derivative. The introduction of the last component leads to altered viscosity properties, and enables the interpolymers to be cured with diamine compounds. The polymers are prepared with a catalyst system of an alkyl aluminum halide and an organic peroxide.
摘要:
An antioxidant composition especially suitable for synthetic lubricants comprises a mixture of (A) one or more oxidised diarylamines e.g. oxidised di-t-octyl diphenylamine, and (B) one or more thiodiarylamines, e.g. phenothiazine. Marked synergism is shown between A and B.
摘要:
A lubricant composition comprised of a major amount of a synthetic ester oil having an inherent Ryder gear load-carrying ability of less than 2200 pounds per inch and a minor, loadcarrying improving amount of a mono-, di- or trihydrocarbyl ammonium salt of an organic carboxylic acid exhibits improved Ryder gear load-carrying ability.
摘要:
A desulfurization catalyst which comprises a cogel of catalytically active amounts of a hydrogenation component which includes a Group VIB or VIII metal, or both, and a Group IVA metal, notably germanium, and a porous inorganic oxide support, notably alumina. Such catalysts are particularly effective in the hydrodesulfurization of naphthas, gas oils, whole heavy crudes and residua.
摘要:
Organophosphorus compounds, characterized by the following structural formula:
wherein Z is a C1 to C6 alkyl-O-CH2 group; X is either O or S; R1 is a C1 to C6 alkyl group; R2 is one selected from the group consisting of C1 to C20 aliphatic, C6 to C10 aromatic and heterocyclic moiety containing 3 to 8 carbon atoms, have been shown to possess insecticidal properties.
摘要:
Novel polyamides are prepared by reacting a dicarboxylic acid with 1,4-cyclohexane-bis( Beta -ethylamine). Unique properties are obtained where the dicarboxylic acid is 1,4-cyclohexane diacetic acid.
摘要:
The strip tensile strength of nonwoven mat battery separators of polypropylene fibers having a diameter from about 1 to about 10 microns is increased, for example, to strengths greater than 4,000 m, by fuse-bonding, as by calendering or point-bonding, at least a portion of the fibers of the mat at temperatures within the range from about 250*F to about 325*F, preferably, from about 280*F to about 315*F, while the mat is subjected to pressure sufficient to prevent shrinkage of the fibers in the mat.
