Abstract
A method for preparing vanillin through a sodium isoeugenol process relates to the technical field of the chemical industry. The method comprises the following steps: mixing sodium isoeugenol and water, adding the obtained mixture into an oxidation reaction kettle, carrying out an oxidation reaction, connecting with a vent pipe to input ozone, increasing the ozone rate to drive the stirring and overturning of a liquid in the oxidation reaction kettle in order to carry out a liquid phase oxidation reaction, layering the liquid obtained after the liquid phase oxidation reaction, adding a sodium sulfite solution to decompose ozonides, neutralizing the ozonides, washing with water to obtain crude vanillin, adding to a refining kettle, carrying out refining crystallization, drying to obtain finished vanillin, packaging and warehousing. The method has the advantages of convenient and simple preparation, environmental protection, no pollution, less equipment investment, high purity and convenient operation, and the prepared vanillin has the advantages of good use effect, safety and reliability.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to the method for a kind of isoeugenol sodium legal system for vanillin food grade,1000.000000ine mesh.
Background technology
Vanillin food grade,1000.000000ine mesh, has another name called Vanillin, for the widely used edible spices of one, can in the seed of vanilla, find, also can synthetic, there is strong milk breath.Be widely used in the various blending food that need to increase milk breath, as cake, cold drink, chocolate, candy; Also can be used for perfumed soap, toothpaste, perfume, rubber, plastics, pharmaceuticals.Vanillin food grade,1000.000000ine mesh is one of important flavouring agent, it is edible deodorant tune, there is XIANGJIALANDOU fragrance and strong milk, it is indispensable important source material in foodstuff additive industry, be widely used in the various blending food that need to increase milk breath, as played flavouring and fixation effect in cake, cold drink, chocolate, candy, biscuit, instant noodles, bread and tobacco, blending drinks, toothpaste, soap, perfume, makeup, ice-creams, beverage and daily cosmetics.Vanillin food grade,1000.000000ine mesh Application Areas is abroad very wide, in a large number for the production of medicine intermediate, also produces conductive agent etc. for plant growth promoter, sterilant, lubricating oil antifoams, brightening agent, printed circuit board.Domestic vanillin food grade,1000.000000ine mesh is mainly used in foodstuff additive, constantly widens in recent years in the application of field of medicaments, has become vanillin food grade,1000.000000ine mesh and has applied most potential field.Current domestic vanillin food grade,1000.000000ine mesh consumption: foodstuffs industry accounts for 55%, and medicine intermediate accounts for 30%, and feed seasonings accounts for 10%, and makeup etc. account for 5%.Both at home and abroad Industry China is vanillin food grade,1000.000000ine mesh big export country of the world, and 2350 tons of domestic needs amounts in 2002, account for 30% of output, and all the other are 70% for outlet.And 1988 be only outlet 273 tons, within 1993, be 1700 tons, within 2002, be 4653 tons.1993～2002 years, Chinese vanillin food grade,1000.000000ine mesh export volume average growth rate per annum was 12%, and traditional vanillin food grade,1000.000000ine mesh production technique is comparatively complicated, and the purity of producing is lower, is difficult to meet human wants.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of purity high, prepares the method for simple and easy and free of contamination isoeugenol sodium legal system for vanillin food grade,1000.000000ine mesh.
Technical problem to be solved by this invention realizes by the following technical solutions:
Isoeugenol sodium legal system, for a method for vanillin food grade,1000.000000ine mesh, is characterized in that: comprise following processing step,
A. isoeugenol sodium and water are mixed to add and in oxidizing reactor, carry out oxidizing reaction.
B. by the still apical grafting ventpipe of oxidizing reactor and input ozone.
C. the speed that increases ozone drives the liquid agitation in oxidizing reactor to stir to carry out liquid phase oxidation reaction.
D. the liquid after oxidation being finished drops into and carries out layering, then adds sodium sulfite solution ozone decomposition compound.
E. ozonide is neutralized, then washing just obtains crude vanillin.
F. crude vanillin is dropped in exquisite still and carry out meticulous crystallization treatment, after being then dried, obtain finished product, packaging warehouse-in.
The waste water input accumulator tank system producing in described steps d decomposes.
The invention has the beneficial effects as follows: the present invention is easy to prepare simple, and environment friendly and pollution-free, facility investment is few, and purity is high, convenient operation, the vanillin food grade,1000.000000ine mesh result of use of preparation is good, safe and reliable.
