摘要:
Esteramine compositions and their derivatives are disclosed. The esteramines comprise a reaction product of a metathesis-derived C10-C17 monounsaturated 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 C10-C17 monounsaturated 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.
摘要:
A chocolate having good solidification properties, a high mold releasability and a high crystal stabilization rate, said chocolate being obtained by using an oil or fat composition wherein StOSt and POP triglycerides are contained each in a definite amount or more and StLSt, PLP, StStO and PPO triglycerides are contained each in a definite amount or less. As a result, the productivity of the chocolate can be increased.

The present invention relates to an interesterified oil composition and a process for preparing such. It has solid fat content values of: from 50 to 70 % solids at 0°C, from 50 to 67% solids at 5°C, from 40 to 62% solids at 10°C, from 20 to 47% solids at 15°C, from 5 to 25% solids at 20°C, and from 0 to 5% solids at 25°C. It further relates to a food product selected from bakery products, confectionery, ice cream, dairy products, oil-in-water emulsions, water-in-oil emulsions, margarines, shortening, spreads, beverages, frozen ready-to-eat dishes, blends with animal fat, comprising food ingredients and 0.1 to 90 weight % of the oil composition according to present invention. In addition it relates to the use of oil composition for preparing food, feed, pharmacy, industrial products, personal care and cosmetics.

The present invention improves biodiesel production in several ways. Unique combinations of unit operations and flow configurations are disclosed in mobile processing units that are feedstock-flexible and can be dynamically deployed in a distributed way. In some embodiments, a process includes introducing a waste oil and an alcohol into a reactor with an esterification-transesterification enzymatic catalyst. Free fatty acids are reacted with alcohol to produce fatty acid alkyl esters, and glycerides are reacted with alcohol to produce fatty acid alkyl esters and glycerin. A membrane separator removes glycerin, water, and alcohol. Unreacted free fatty acids are then separated and recycled, to generate a product stream with fatty acid alkyl esters. A genset may be provided for combusting glycerin to produce electrical power and thermal heat as co-products. This biodiesel process may be energy self-sufficient, require no external utilities, and avoid direct discharge of wastewater.
摘要:
A process for producing triglycerides which comprises: (a) subjecting a first triglyceride comprising at least 40 % by moles of oleic acid residues, based on total acyl groups in the triglyceride, to an alcoholysis reaction with an alcohol having from 1 to 6 carbon atoms to obtain a composition comprising 2- oleoyl monoglyceride and at least one acyl ester of said alcohol; (b) reacting the 2-oleoyl monoglyceride with an acylating agent comprising at least one C12 to C24 saturated fatty acid, at least one ester of said fatty acid or a mixture thereof, to obtain a 1,3- saturated fatty acid acyl 2-oleoyl glyceride; and (c) separating at least a part of the at least one acyl ester after or during step (a) or step (b); (d) reacting the acyl ester with a second glyceride to form 1,3- dioleoyl 2-palmitoyl glyceride.
