Epoxy-containing compounds which are essentially free of organic halides are prepared by (I) reacting an allyl derivative of an active hydrogen-containing compound with (II) a peroxygen-containing compound. The epoxy-containing compounds are useful in coatings, castings, laminates etc.

Process for preparation of epoxy compounds essentially free of organic

The present invention is directed to a process for producing (-) 2-substituted-ornithines comprising contacting a 2-substituted-piperidone with L-.alpha.-E-aminocaprolactam-hydrolas in the presence of a divalent cation.

Method for the production of (-)-4-difluoromethyl-ornithine

Glycidyl esters are prepared by reacting a compound containing one or more ethylenically unsaturated ester groups with hydrogen peroxide in the presence of an alkali metal or alkaline earth metal salt of tungstic acid, phosphoric acid and a phase transfer catalyst, optionally in the presence of one or more solvents.

Preparation of glycidyl esters

Included are novel perhydro-s-triazine derivatives, tentacular-perhydro-s-triazines. For example, 1,3,5-triazine-1,3,5-(2H,4H,6H)triethanol dioleate; 1,3,5-triazine-1,3,5-(2H,4H,6H)triethanethiol trioleate; and 1,3,5-triazine-1,3,5-(2H,4H,6H)tris(morpholinoethane) are included. The derivatives are corrosion inhibitors for metals. the compounds may also be used as emulsifiers, lubricants and hydraulic fluids.

Disclosed as a novel compound is cyano-(2,4-dichlorophenyl)methyl ethyl ester of carbonic acid. This compound has utility as a nematocide.

Cyano-(2,4-dichlorophenyl)methyl ethyl ester of carbonic acid useful as

N-substituted perhydro-s-triazine compounds can be used to increase the solubility of alkali or alkaline earth metal salts in an organic medium. Increasing the solubility of such salts catalyzes the reaction between the salts and other components of the organic medium. For example, 5 percent of a tris(n-octylpolyoxyethylene)-N,N',N'-perhydro-s-triazine compound catalyzes the reaction between sodium iodide and n-octyl bromide at 80.degree. C. for 1 hour to form 100 percent yield of n-octyl iodide.
