Abstract
The present invention provides one-step predextrination process of preparing cold soluble particular cationic starch. While predextrination of starch material, cationic etherifying agent and dexstrinated starch produce homogeneous reaction with the reaction rate of reagent being raised to over 95%. The said simple method can produce granular powder product capable of being gelatinated in cold water at low cost.
Description
The invention belongs to the chemical modification of starch method.
Cationic starch can be used as purposes such as flocculation agent, paper making intensifier and retention aid, sewage-treating agent, tackiness agent.In the prior art about the manufacture method of particular cationic starch, be earlier with starch by the cationization reaction after, more after filtration, washing, drying and other steps make the particular cationic dry starch.In use again with the dry powder redispersion in water, can use after become sticking with paste through boiling.This just makes that step is various and complicated in production and application process, and cost also increases, (U.S3778431, WP92-109316, WP87-006870) report.File is also arranged, and (U.S3770472 U.S5604085) be reported in the use scene and prepare gluey water-dispersion build cationic starch paste on the spot, but this can only now do existing usefulness, and all there are very big difficulty in packing, transportation, storage, therefore are difficult to commercialization.
The present invention is to provide a kind of method that adopts pre-gelatinization prepared particular cationic starch, can overcome the deficiency that exists in the above-mentioned prior art, a step is finished the cationization reaction.This method reacts raw starch and positively charged ion donor with alkali as a catalyst.The both available synthetics cationic etherifying agent of positively charged ion donor, also available cationoid reagent and the monomeric blend of bridge agent.The cationic etherifying agent that is suitable for has four classes: alkyl aminoethyl muriate; 2,3-epoxypropyl trialkyl ammonium salts; 4-chloro-crotyl alkylammonium salt; Alkyl ammonia nitrile compound.The cationic reagent that is suitable for is: Trimethylamine 99, triethylamine, dimethylamine, diethylamine, amino piperazine, pyridine alkane etc.; The multi-functional bridging agent that is suitable for is: both had a functional group and combined with cationoid reagent, have again a functional group under base catalysis can with the hydroxyl reaction of starch, bridging agent can be wire, ring-type, heterocycle shape, aromatic series etc.
The characteristics of this method are to make pasted starch and cationic etherifying agent be equal phase reaction by pre-gelatinization technology, 80～170 ℃ of temperature of reaction, and in 1～10 minute reaction times, resultant need not filter and be dry, and its basic recipe comprises:
100 parts of starch
Tap water 100-2000 part
Solid alkali 1-10 part
Etherifying agent 3-16 part
Reaction method is that starch is starched with tap water furnishing powder earlier, and dripping alkali liquid and etherifying agent remain between the PH9-11 farinaceous size again, then the powder slurry is flowed in the rotary dryer, makes the reaction of pasted starch and etherifying agent.Also can directly in starch slurry, add cationoid reagent and bridging agent, add alkali lye again and transfer PH=9-11, flow in the rotary dryer again after stirring and react.For avoiding the bridging agent cross-linking starch, in the prescription if with ative starch then powder slurry concentration should be lower than 5%; Powder slurry concentration as if then being made into degraded starch about 30% is no more than 5 minutes with the reaction time, can prevent or reduce cross-linking of starch like this.
Method provided by the present invention can make the reactivity of etherifying agent bring up to more than 95%, and technology is easy, and a step is finished cationization reaction, and product is that particulate state dry powder again can easily gelation in cold water, and is easy to use.
The present invention and original processing method be at material consumption, the contrast of aspects such as reaction conditions and product performance such as following table:
