Description
Technical field
The present invention relates to a kind of modified starch, particularly a kind of with water chestnut starch for the technique of succinate ester of starch prepared by raw material, belong to chemical industry synthesis field.
Background technology
Starch, as a kind of natural resource of extensive existence, has become important industrial raw material.Some inherent naturies due to native starch: cold water is insoluble, stick with paste liquid in acid, heat, unstable etc. under shearing action, limit application in the industry, therefore people develop the sex change technology of starch according to the structure of starch and physico-chemical property, namely use the method for physics, chemistry and enzyme, ative starch is processed, make it have the character of certain special purpose applicable, this process is exactly the sex change of starch, and its product is exactly modified starch.Modified starch has unique good characteristic, is widely used in the fields such as weaving, food, papermaking, same to articles for use, makeup, industrial and agricultural production.How further controlled denaturation starch denaturalization degree, expansion sex change kind, the raw material input amount that reduces, reduction byproduct of reaction productive rate, be all significant for performance, the raising economic benefits improving modified starch.
The output of current whole world modified starch is about 7,000,000 tons, wherein about 2,600,000 tons, the U.S., about 1,000,000 tons, European Union.In recent years, modified starch has had in China and has developed faster, and be widely used in industrial production, range of product has expanded to tens series up to a hundred kinds.Esterification starch is exactly the one in modified starch, due to its distinctive character, is applied widely in the industry.Esterification starch just refers to the class modified starch that the hydroxyl in starch structure is obtained by organic acid or mineral acid esterification.Different according to the sour kind that esterification occurs, be divided into two large classes: one is starch organic acid acetic, and two is starch inorganic acid esters.
Starch organic ester is the kind of starch derivative utilizing the hydroxyl of starch and organic acid (acid anhydride) to be generated by esterification, and starch organic ester is widely used in all trades and professions as degradable, ep-type material.Hydrophobicity due to general organic acid acetic can improve the sizing performance of starch to hydrophobic synthetic fibre, therefore the use of organosilane ester modified starch in textile warp starching is particularly noticeable.They, while the excellent biodegradability of succession ative starch, also in the defect improving ative starch in varying degrees, compensate for the deficiency of ative starch in slashing process.
In starch organic ester, the research of acetate starch is fairly widespread and deep, but general preparation technology's yield rate is not high.Water chestnut is containing a large amount of starch, and starch accounts for more than 86% of dry weight, and the present invention for raw material, prepares a kind of water chestnut succinate ester of starch with natural water chestnut starch, and its preparation technology is simple, and yield rate is high.
Summary of the invention
The object of this invention is to provide a kind of preparation technology of water chestnut succinate ester of starch, its step of preparation process is as follows:
(1) get and a certain amount of water chestnut ative starch is loaded in container, add distilled water, and constantly stir with agitator, starch small grain is dissolved in water;
(2) pour the NaOH solution of certain solubility again into, the pH value of regulator solution;
(3), under continuous agitation condition, add Succinic anhydried, reaction for some time;
(4) add the HCl solution of certain solubility again toward solution system, the pH value of adjustment solution is neutral;
(5) again solution is filtered, and collects filtration product,
(6) product is poured in acetone soln, refilters,
(7) again precipitation is washed with water, and filter;
(8) filtration product is put into vacuum-drying, obtain a kind of water chestnut succinate ester of starch.
Preferentially, step (2) in, the solubility of NaOH solution is 1-2mol/mL.
Preferentially, step (2) in, the PH of regulator solution controls between 9-10.
Preferentially, step (3) in, the reaction times controls at 15-30 minute.
Preferentially, step (4) in, the solubility of HCl solution is 1-1.5mol/mL.
The present invention has following advantages and characteristic:
(1) preparation technology is simple, flow process is short;
(2) abundant raw material, cheap.
