Description
Technical field
The present invention relates to emulsion dispersion technical field, particularly relate to a kind of efficient emulsification dispersion system for glucosides production and emulsion dispersion method.
Background technology
APG (APG for short) is that twentieth century starts an industrialized class novel non-ionic surface active agent the nineties.APG is by the hemiacetal hydroxyl of glucose and fatty alcohol hydroxyl, under the catalysis of acid, lose one divided water and mix products (the single glycosides obtained, two glycosides, three glycosides etc., therefore also known as alkyl polyglycoside), its general formula of molecular structure is RO (G) n, and wherein sugar unit is hydrophilic group, and the alkane of long-chain or side chain is lipophilic group.APG is moisture absorption solid, and pure APG is white powder, in industrial goods due to containing impurity in faint yellow or light yellow.APG is water-soluble, and product is made generally in the aqueous solution of 50 ~ 70%.
Compared with other surfactants, the features such as alkyl glucoside surfactant has that surface tension is low, stable in strong detergency, alkaline environment, compound property is splendid, and little to skin irritation, toxicity is low, simultaneously because it is with glucose and fatty alcohol preparation, therefore biological degradability is good, environmentally safe.Its superior performance, has development potentiality, is widely used in the industrial circles such as washing, cosmetics, food.As a kind of novel surfactant of environmental protection, in recent years, about the research of APG becomes one of the research field and developing focus that surfactant enlivens the most day by day.
The first step that APG is produced is the mixing and emulsifying of glucose and fatty alcohol, but in the process of actual production glucose and fatty alcohol immiscible, the reaction of therefore synthesizing APG is liquid-solid two-phase reaction, is subject to the impact of glucose granularity.Generally, glucose granularity is too large, decision reaction speed is slow, glycan amount increases, general emulsifying device easily causes glucose precipitation, the not first-class mixing and emulsifying non-uniform phenomenon of granular size, even in mixing and emulsifying system, cause pipeline Severe blockage, glucose coking etc., the reaction of guanosine causing glucose follow-up is not thorough, reaction easily occurs that the materials such as polysaccharide glycosides, glycan produce, it is defective that APG produces product, brings directly and indirectly cost increase, cause the serious consequence such as environmental pollution and the wasting of resources to enterprise.

For an emulsion dispersion method for the efficient emulsification dispersion system that glucosides is produced, comprise the steps:
(1) feed back control valve, is opened, close discharging control valve, start emulsion dispersion machine, all join in mixing emulsifier from fatty alcohol charge door by disposable for the quantitative fatty alcohol needed for emulsion dispersion, under the stirring action of emulsion dispersion machine, fatty alcohol is back in mixing emulsifier through discharging opening, discharge pipe, conveying type emulsification pump, feed back pipeline and feedback outlet, forms Inner eycle;
(2), under Inner eycle state, quantifying glucose needed for emulsion dispersion is joined in mixing emulsifier from glucose charge door in batches, while emulsion dispersion machine carries out fragmentation, emulsification, the mixture of glucose and fatty alcohol is back in mixing emulsifier through discharging opening, discharge pipe, conveying type emulsification pump, feed back pipeline and feedback outlet, form Inner eycle, the quantifying glucose that Inner eycle continues to needed for emulsion dispersion all adds rear half an hour;
(3), close feed back control valve, open discharging control valve, the mixture completing the fatty alcohol and glucose of emulsion dispersion exports from output channel through feed back pipeline after the discharging opening of mixing emulsifier flows out.
Beneficial effect: be provided with Inner eycle loop in efficient emulsification dispersion system of the present invention, glucose is under Inner eycle state at fatty alcohol to be joined in mixing emulsifier, through fragmentation, the emulsification of emulsion dispersion machine, the granular size of glucose becomes consistent, simultaneously its dispersion in fatty alcohol becomes even, and finely dispersed glucose and fatty alcohol are back in mixing emulsifier through Inner eycle loop and form Inner eycle.In inner cyclic process, glucose joins in mixing emulsifier in batches and carries out emulsion dispersion with fatty alcohol, until glucose adds rear half an hour, the Inner eycle of glucose and fatty alcohol terminates, and final both complete sufficient emulsion dispersion.In this process, dextran particles is in suspending and floating shape in fatty alcohol, deposited phenomenon can not occur.Wherein, owing to Inner eycle loop being provided with conveying type emulsification pump, making the mixture in Inner eycle loop have certain pressure, not easily cause the blocking of pipeline.Emulsification dispersion system of the present invention makes glucose and fatty alcohol mixing be uniformly dispersed; glucosides yield is high, the reaction time is short, glycosidation synthetic route is short, energy consumption is little, easy to operate and low cost and other advantages to bring to follow-up glucuronidation reaction system; produce qualified products to APG and provide guarantee; reduce cost of investment and the production cost of APG production, increase the benefit; perfect mixing and emulsifying decentralized system stablizes the requirement with safety operation; improve the technique drawback of emulsification dispersion system; pollution-free, be conducive to environmental protection.
