Esteramine compositions and their derivatives are disclosed. The esteramines comprise a reaction product of a metathesis-derived C-Cmonounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a tertiary alkanolamine. Derivatives made by quaternizing, sulfonating, alkoxylating, sulfating, and/or sulfitating the esteramines are also disclosed. In one aspect, the ester derivative of the C-Cmonounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The esteramines and derivatives are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), antimicrobial compositions, agricultural uses, and oil field applications.

Esteramines and derivatives from natural oil metathesis

Esteramine compositions and their derivatives are disclosed. The esteramines comprise a reaction product of a metathesis-derived C-Cmonounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a tertiary alkanolamine. Derivatives made by quaternizing, sulfonating, alkoxylating, sulfating, and/or sulfating the esteramines are also disclosed. In one aspect, the ester derivative of the C-Cmonounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The esteramines and derivatives are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), antimicrobial compositions, agricultural uses, and oil field applications.

Provided are methods for decreasing the reaction time between an alkanolamine such as triethanolamine and a fatty acid alkyl ester such as, a triglyceride, a vegetable oil, a methyl ester, an ethyl ester, etc., a fatty acid, or a mixture thereof. The methods utilize a divalent zinc catalyst to facilitate and accelerate an esterification or transesterification reaction between the alkanolamine and the fatty acid, or fatty acid alkyl ester.

Catalyst for esteramine production

Soap bar compositions comprising alpha sulfonated fatty acid alkyl esters and long chain fatty acids

Disclosed are compositions suitable for formation into mild personal cleansing or laundry detergent bars, as well as other uses. The compositions generally comprise:

Soap bar compositions comprising alpha sulfonated fatty acid alkyl

Disclosed is a process for the preparation of primary, secondary and tertiary amines with high conversion and high selectivity via low pressure catalytic hydrogenation of unsubstituted, N-substituted, and N,N-disubstituted amides. Amide hydrogenation is conducted using a catalyst system comprising copper chromite and a nucleophilic reagent, in combination with hydrogen gas. The process allows for production of amines which may be directly used as chemical intermediates in the manufacture of surfactants, quaternary ammonium compounds, bactericides, disinfectants, lubricants, petroleum additives, ion exchange resins and the like, without the need of purification, such as distillation.

Process for the conversion of fatty amides to amines

The invention encompasses methods for preparing in high purity and in high yield p-phenyl sulfonic acid acyl glycolates of the formula ##STR1## where R represents branched or straight chain alkyl having 6-12 carbon atoms by treating a phenyl ester or phenyl acyl glycolate of the formula ##STR2## where R represents branched or straight chain alkyl having 6-12 carbon atoms with a sulfonating agent to form intermediate sulfonation; transmuting the intermediate sulfonation products; and quenching the transmuted intermediate sulfonation products with a quenching reagent reactive with sulfur trioxide.
