A method for producing an amine. The first step is contacting a cyanide, an acid, water and a substrate compound capable of generating a carbonium ion by reaction with the acid to generate a first reaction intermediate. The second step is contacting the first reaction intermediate with water to form a second reaction intermediate. The third step is removing cyanide present in the second reaction intermediate to a concentration less than 10 ppm. The fourth step is contacting the second reaction intermediate with an alkali metal hydroxide to form the amine.

Process for preparation of tertiary alkyl primary amines

A method for producing a nitrone of formula (I) wherein R is a branched alkyl group having from four to thirty carbon atoms; R, R, Rand Rindependently are hydrogen or alkyl groups having from one to six carbon atoms from an imine having formula (II) 

Preparation of nitrones

A composition comprising: (i) a chelating aminocarboxylic acid-C-Camine complex; (ii) a C-Cbis(2-hydroxyethyl)amide; and (iii) a C-Cimidazoline compound.

Formulations useful as asphaltene dispersants in petroleum products

Novel amine-chelate complexes are useful in significantly reducing the viscosity of heavy crude oils, facilitating the recovery and transportation of such heavy crude oils. The amine-chelate complexes are formed by heating together an organic amine with a chelating agent.

Recovery and transportation of heavy crude oils

A method for making an amine includes the steps of heating a reaction mixture including a nitrile, an acid, water and a substrate compound capable of generating a carbonium ion by reaction with the acid to generate a first reaction intermediate; treating the first reaction intermediate with an acid in the presence of a primary alkanol to form a second reaction intermediate and an alkyl ester; separating the alkyl ester from the second reaction intermediate; and treating the second reaction intermediate with a base to form the amine.

Method for making an amine and an alkyl ester and method for reducing

A method for removing hydrogen cyanide from a hydrogen cyanide-contaminated organic liquid includes the steps of contacting the hydrogen cyanide-contaminated organic liquid with a metal alkoxide to generate a metal cyanide salt and an alkanol and then separating the organic liquid from the metal cyanide salt and the alkanol.
