摘要:
Novel phosphorus element-containing crosslinking agents for epoxy resin compositions based on an isomeric mixture of tris(2-hydroxyphenyl)-phosphine oxide compounds. Epoxy resins cured or crosslinked with the crosslinking agents of this invention yield non-halogenated, ignition resistant epoxy resin formulations. The ignition resistant epoxy resin formulations are advantageously used for making laminates for printed wiring boards and composite materials.

摘要:
A novel method for the preparation of aryl trifluoromethyl ethers which comprises reacting a phenol, a perhalomethane, and an antimony pentahalide. For example, 4-nitrophenol may be reacted with an excess over stoichiometry of both carbon tetrachloride and antimony trifluoride with a catalytic amount of antimony pentachloride to form 4-nitrophenyl trifluoromethyl ether.
摘要:
Alkyl aryl sulfones are disclosed which are useful as high temperature and magnetic recording media lubricants. Also disclosed are lubricating mixtures containing the alkyl aryl sulfones, magnetic recording media containing the alkyl aryl sulfones, and a process for lubricating the magnetic recording media with the alkyl aryl sulfones.
摘要:
A lubricating composition which comprises a lubricating fluid and an aryl arenesulfonate in an amount sufficient to increase the lubricity of the lubricating fluid. A process for increasing the lubricity of a lubricating fluid which comprises adding an aryl arenesulfonate to the lubricating fluid in an amount greater than or equal to about 0.5 percent and less than or equal to about 5 percent based on the weight of the lubricating fluid.
摘要:
This invention relates to digestively hydrolyzable low calorie edible oil substitutes. These compounds have the organoleptic properties of normal triglycerides fats, but are lower in available calories. Specifically, the invention is directed to a composition of matter. The compositions are in one embodiment amides of dimer acids or trimer acids made from glycinates. The compounds are in part directed to amides based on the amino acid esters of the amino acid glycine. The utility of these compounds is in a low caloric edible oil.
