発明の名称 (英語) PROCESS FOR PRODUCING SUGAR FATTY ACID ESTER USING ANION EXCHANGER AS CATALYST
発明の概要(英語) The purpose of the present invention is to provide a process for producing a sugar fatty acid ester such as sucrose fatty acid ester (FASuc) and provide a composition containing the sugar fatty acid ester, the process solving the various problems of conventional processes for producing such esters. The process has advantages including no generation of a by-product soap and ease of separation between the catalyst and the reaction product, and enables the ester to be efficiently synthesized in a flow system by a simple operation under mild conditions. The present invention relates to: a process for producing a sugar fatty acid ester by transesterification between a fatty acid ester and a sugar using an anion exchanger as a catalyst; and a composition containing the sugar fatty acid ester.
従来技術、競合技術の概要(英語) BACKGROUND ART
The sugar is sucrose (Suc), about 1.8 billion tons per year it is said that the amount of production, as a single organic compound, having the largest production scale, high-purity products be available at low cost, various usages as a chemical raw material has been proposed. Current, and the industrial production as one of sucrose derivative, sucrose fatty acid ester is (FASuc).
Is FASuc, hydrophilic groups and lipophilic groups Suc FA is derived from vegetable oil fatty acid and an ester bond of the non-ionic surfactant. 8 Combine with the hydroxyl group of a sucrose fatty acid by the number of hydrophilic, lipophilic can be changed, a wide variety of hydrophilic, lipophilic balance (HLB) value. Is FASuc, in addition to the emulsifying action, the solubilizing ability, dispersing ability, has high functionality such as a lubricating ability.
In addition, in recent years, the pharmaceutical field, for use as a binder of tablets FASuc the studies performed, the pharmaceutical field is expected to be also used.
In this way, the FASuc, sugar produced from vegetable oils and inexpensive with high added value of the biomass-derived in a chemical, hydrophilic fatty acid and low miscibility Suc are difficult to be synthesized are known.
Current, industrial production processes are FASuc, dimethyl sulfoxide (DMSO) of the amphiphilic solvent is used, an Na phase equalizing2 CO3 Suc and fatty acid methyl esters catalyzed transesterification reaction (FAMe) has been used.
However, in order to enhance the conversion rate of the byproduct methanol (MeOH) is essential to the vacuum condition is removed, the catalyst by the reaction of the byproduct soap FAMe, uniform phase separation of the catalyst difficult, non-continuous operation, and has a problem, a factor of high cost. In order to cope with such a problem, for example, a packed column and a plurality of the condenser placed in series with the reactor, the second stage condenser 1 is filled with a liquid condensation reflux to the top of the tower are proposed (Patent Document 1).
Of another manufacturing method is the industrial FASuc, without using a catalyst and an organic solvent, an ester exchange an attempt has also been performed (Patent Document 2 and Patent Document 3). For example, to Patent Document 3, an aqueous solution of sucrose fatty acid methyl ester as an emulsifying agent was added to the sugar fatty acid ester, ultrasound and microwave was irradiated to the emulsion to a method to promote the reaction and have been described.
On the other hand, the inventors of the present invention, the fat and fatty alcohols and fatty acid esters by transesterification reaction in the method of manufacturing, the anion exchange body is used as a catalyst, an alcohol and fats 1/30-1/1 in the molar ratio of the fatty acid ester and a manufacturing method (Patent Document 4).
In addition, as a manufacturing method of the sucrose fatty acid ester, sucrose fatty acid glycerides or a lower alkanol and an alkali metal ion-exchanged cation exchange resin in the presence of the ester exchange reaction method is disclosed (Patent Document 5). However, a functional group having a quaternary ammonium group as the basic anion exchange resin having functional group of tertiary amine or a basic anion exchange resin is used when the reaction is not obtained satisfactory results have been described (Patent Document 5, page 4 left column).
