Description
Technical field
The invention belongs to modified starch preparing technical field, be specifically related to a kind of ultrasound wave-mechanical activation solid phase method and prepare
The method of environment-friendly type modified starch.
Background technology
Starch ester is a kind of important kind of modified starch, refers to that the hydroxyl in starch structure is by organic acid or inorganic acid ester
The class modified starch changed and obtain.Current starch esterification product mainly has starch acetate, starch phosphate, starch xanthan
The short chain organic acid such as acid esters, starch nitrate or inorganic acid ester, and starch stearate, starch octenyl succinate anhydride are isometric
Chain starch ester.But the research for starch double esterification complex denaturation is less.Although mono-esterification starch has more more preferable than ative starch
Processing characteristics, but often performance is single, by meeting the higher processing request that the modern life is proposed, the exploitation of composite modified starch
With the main flow that application becomes current starch denaturalization.Xiao Tiantian, with corn starch as raw material, uses ultrasonic pretreatment technology to shallow lake
Powder carries out pretreatment, more successively with sodium trimetaphosphate and acetic anhydride as esterifying agent, prepares initially with semidry method ultrasonic response
Organic phosphate starch, then use Wet Method Reaction to prepare double esterification corn starch gained esterification starch and acetic anhydride, application
Preparation in dried noodles.Feng Lin etc., with succinic anhydrides and acetic anhydride for complex ester agent, carry out complex denaturation reaction to starch, knot
Fruit shows that compound esterification starch performance feature has clear improvement.Liu Peiling etc. are beautiful with adipic acid and acetic anhydride mixed acid crosslinking Treatment
Rice starch, prepares the amorphous particulate form starch containing only impalpable structure.
The subject matter that the preparation of traditional double esterification starch and application exist: prepared by liquid phase, application surface is narrow, degree of esterification is low
Deng.Mostly the double esterification starch that China produces now is to produce in a wet process, because the mass-transfer efficiency of wet method is high, can make starch and reagent
Being fully contacted, reaction efficiency is high, and production process is easy to control, but its shortcoming to be water consumption big, pollute big, product drying process consumes
Can be big.The most traditional double esterification starch is mostly inorganic acid ester, and organic acid esters particularly long chain organic acid ester is then reported less.
No matter the method studying starch double esterification at present, use which kind of to strengthen reactive measures, and its esterification reaction process is all at water or to have
Machine solvent is carried out, and the rarely seen research having in terms of solid phase esterification modification.Solvent method needs substantial amounts of solvent, there is solvent and returns
Receive, pollute environment, catalyst residual, complex process and the shortcoming such as relatively costly.Therefore, more effective starch esterification side is found
Method, makes esterification process simplification, pollution-freeization, and synthesis double esterification starch is significant at a low price.
Mechanical activation (Mechanical Activation) is an emerging overlapping edges technology, refers to solid matter
Rubbing, collide, impact, under the mechanical force such as shearing, make crystal structure and physical and chemical performance change, make some mechanical energy
Being transformed into the interior energy of material, thus cause the chemism of solid to increase, it belongs to the category of mechanical force and chemical.Mechanical activation has
Have the following advantages: the response time is short, easy to operate, it is easy to control.From nineteen fifty-one, Peters etc. has made a large amount of about mechanical force
The research work of induced chemical reaction, explicitly points out the chemical reaction that mechano-chemical reation is mechanical force induction, highlights machine
The effect of tool power, thus mechanical force and chemical causes the whole world and pays close attention to widely.In recent years, mechanical force and chemical technology obtains very
Great development, is widely used in preparing ultra micro and nanometer powder, nano composite material, strengthened dispersion alloy structural material, metal essence
Refining, mineral and refuse process, Polymer Synthesizing etc..Wherein polymerization material resources chemosynthesis is noticeable, and it is under force field,
Polymer produces intramolecular stress, and then makes molecular chain rupture, forms two big free radicals, and this big free radical typically has relatively
Strong activity, it can be stablized with free-radical acceptor effects such as oxygen molecules, makes polymer molecular weight reduce and realizes degraded,
Polymerisable monomer synthesis block or graft copolymer can also be caused, even can also be straight with other polymer of active point
Connect formation graft copolymer.The advantage of its uniqueness is had, it is not necessary to solvent, symbol owing to polymer mechanochemical method carries out Macroscopic single crystal
Cyclization guaranteed request, it is not necessary to add extra equipment, economically feasible.Polymer is blended and is worldwide subject to the most in recent years
Pay attention to, become and prepare novel, a kind of simple and easy to do method of high performance material.
Summary of the invention
The present invention provides the preparation method of a kind of environment-friendly type modified starch, multiple to solve prior art preparation process operation
Miscellaneous, cycle length, reaction relate to that liquid phase is wayward causes cost high, and the problems such as starch utilization ratio is low, the method for the present invention overcomes
The problems such as wet production (liquid-phase condition) process is wayward, degree of esterification is low, production cycle length, obtained environment-friendly type becomes
