Description

A kind of fractional extraction method of sucrose fatty ester
Technical field
The present invention relates to a kind of fractional extraction method of sucrose fatty ester.
Background technology
Sucrose fatty ester is the one or more hydroxyls and C of sucrose8~C22Aliphatic acid be esterified to be formed a class green Nonionic surface active agent, has the advantages that hydrophilic lipophilic balance is wide, emulsifiability is excellent, nontoxic, biodegradable, quilt It is widely used in the industries such as food, medicine, cosmetics.At present, the industrial production of sucrose fatty ester, which is mainly, uses ester-interchange method, It can be subdivided into solvent method and solventless method, the sucrose fatty ester that both approaches are obtained and not only contain sucrose-fatty list Ester, sucrose-fatty diester and sucrose fatty polyester, also containing unreacted sucrose, fatty acid methyl ester (or ethyl ester or glycerine Ester), aliphatic acid potassium (or sodium), the impurity such as catalyst, wherein, the content of sucrose-fatty monoesters generally 20%~55% it Between.Therefore, to expect high-purity, the sucrose fatty ester of high monoester content, it is necessary to sucrose fatty ester carry out purification and Separation.
United States Patent (USP) US 3748324 is using the two-phase solvent dissolution extraction such as butanone/water or ethyl acetate/water sucrose fat Acid esters, and adjust pH value to 3.5~5.0 or add divalent metal salt and remove soap impurity, so as to realize sucrose-fatty The purification of ester.
Chinese patent CN 104004033A use butanone dissolving sucrose fatty acid ester at 70 DEG C, filter out undissolved sucrose Afterwards, CaCl is added in 55 DEG C of stirrings are descended toward filtrate2The aqueous solution, reaction is separated by filtration to obtain filtrate and solid, filtrate warp after 1 hour Wash, distill, being dried to obtain the sucrose fatty ester of low monoester content, solid is through extraction at 70 DEG C of butanone, washing, distillation, dry It is dry, obtain the sucrose fatty ester of high monoester content.
Chinese patent CN 103087118A use butanone, butanol or the ethyl acetate dissolving sucrose fatty acid ester at 55 DEG C, It is directly added into dissolved with CaCl2The NaCl aqueous solution, filter out sediment fatty acid calcium etc., organic layer is washed with brine, after layering, cold But crystallization, obtains purity>98% sucrose fatty ester, monoester content is 20% or so.
In addition, for the separation of the sucrose fatty ester without impurity such as sucrose, soaps, Chinese patent CN The method that 105037450A uses crystallisation by cooling, by adjusting ratio and consumption, the chilling temperature and time of etoh solvent/water, The sucrose fatty ester of isolated different monoester contents.
However, the method generally existing problems with of above-mentioned purification & isolation sucrose fatty ester:1) sucrose fatty ester Total ester, especially monoester content are relatively low, do not reach the requirement of high-end product market;2) complex technical process, sucrose fatty ester The rate of recovery is not high, refines cost high;3) solvent usage amount is big, and the NaCl salt solution introduced in technique can cause saliferous, organic waste The process problem of water, improves cost, adds environmental protection pressure;4) due to needing to add CaCl2、MgSO4Deng divalent metal salt Precipitated fatty acid soap, adds solid waste.
