Description of drawings
Fig. 1, embodiment of the invention process flow sheet.
Each process optimization is analyzed:
1, starch oxidation process optimization:
(1), H
2O
2Add-on is to the influence of viscosity:
Under the situation that be 20% at the massfraction of reaction system water, the pH value is controlled at 8.5～10.5,50 ℃～60 ℃ of oxidizing temperatures, oxidization time 3h remain unchanged, H
2O
2Get 0.3%, 0.5%, 0.8%, 1.0% respectively with the per-cent of ative starch, oxygenant is studied the influence of system viscosity, the results are shown in Table shown in 1;
Table 1 H
2O
2Add-on is to the influence of viscosity:
| Add-on/% | 0.3% | 0.5% | 0.8% | 1.0% |
| Viscosity (6%, 95 ℃, mPas) | 30 | 24 | 9 | 3 |
Along with H
2O
2The increase of add-on, H in the system
2O
2Concentration big more, more free oxygen can be provided, the probability that it contacts with hydroxyl in the starch molecule is big more, react fast more, thereby the amplitude of viscosity degradation also can be big more.
(2), temperature of reaction is to the influence of viscosity:
Be 20% at the massfraction of reaction system water, the pH value is controlled at 8.5～10.5, H
2O
2Add-on is under ative starch 0.5%, the oxidization time 3h situation about remaining unchanged, and has studied the influence of temperature of reaction to viscosity, the results are shown in Table shown in 2;
Table 2 temperature of reaction is to the influence of viscosity:
| Temperature/℃ | 40 | 50 | 60 | 70 |
| Viscosity/(6%, 95 ℃, mPas) | 29 | 26 | 21 | 20 |
H
2O
2Comparatively responsive to temperature, the oxidisability temperature influence is bigger, and H
2O
2At high temperature decompose easily.Therefore, temperature of reaction also is conspicuous to the influence that starch viscosity descends.Along with temperature raises, starch viscosity decline degree increases gradually, but temperature makes viscosity degradation not obvious because of the decomposition of hydrogen peroxide causes oxidisability to reduce when too high, and therefore best temperature of reaction should be at 50 ℃～60 ℃.
(3), the reaction times is to the influence of viscosity:
Be 20% at the massfraction of reaction system water, the pH value is controlled at 8.5～10.5, H
2O
2Add-on is under ative starch 0.5%, 50 ℃～60 ℃ situations about remaining unchanged of temperature of reaction, has studied the influence of oxidization time to system viscosity, the results are shown in Table shown in 3;
Table 3 oxidization time is to the influence of viscosity:
| Time/h | 2 | 3 | 4 | 5 |
| Viscosity/(6%, 95 ℃, mPas) | 32 | 23 | 20 | 20 |
With the increase of oxidization time, viscosity constantly descends, and when oxidization time reached 3h, viscosity was 20mPas, and then with the prolongation in reaction times, viscosity change is little, considers the production cost factor, so the selective reaction time is 3h.
2, starch crosslinking process:
In order to guarantee the good dispersion of product cold water, this project product is adopted low crosslinking degree, and reaction conditions is chosen as: the epoxy chloropropane add-on is 0.004% of a starch, and pH value in reaction is 10～11.5, and temperature of reaction is 50～60 ℃, and the reaction times is 1.5h.
3, starch ethers metallization processes:
(1), NaOH and ClCH
2The COONa mol ratio is to the influence of substitution value:
After above-mentioned optimization process modification, be 20% at the massfraction of reaction system water, ClCH
2The COONa add-on be ative starch 8%, under 60～70 ℃ of etherification temperatures, the etherificate time 3h situation about remaining unchanged, studied NaOH and ClCH
2The COONa mol ratio the results are shown in Table shown in 4 the influence of substitution value (DS);
Table 4 NaOH and ClCH
2The COONa mol ratio is to the influence of substitution value:
| Mol ratio | 1.5 | 2.0 | 2.5 | 3.0 | 3.5 |
| DS | 0.0512 | 0.0857 | 0.119 | 0.107 | 0.0895 |
With the increase of alkali number, substitution value all can correspondingly improve, but when alkali number is too much, can cause ClCH
2COONa and NaOH reaction generate HOCH
2COONa and lose ability with starch reaction, thus the decline of substitution value and reaction efficiency caused, and too much alkali number also can reduce the productive rate of product simultaneously.Therefore, according to the production actual result, NaOH and ClCH
2The COONa molar ratio is the best with 2.5.
(2), temperature of reaction is to the influence of substitution value:
Be 20% at the massfraction of reaction system water, ClCH
2The COONa add-on be ative starch 8%, NaOH and ClCH
2Under the situation that the COONa mol ratio is 2.5, etherificate time 3h remains unchanged, studied the influence of temperature of reaction, the results are shown in Table 5 substitution value (DS);
Table 5 temperature of reaction is to the influence of substitution value:
| Temperature/℃ | 40 | 50 | 60 | 70 | 80 |
| DS | 0.0576 | 0.100 | 0.115 | 0.119 | 0.105 |
The rising temperature of reaction helps the expansion of starch granules and the mobile infiltration of reaction reagent, thereby helps the carrying out of etherification reaction, improves reaction efficiency, shortens the reaction times.When but temperature was too high, starch was easy to generate gel, caused that system is clamminess, operational difficulty, when temperature reaches 80 ℃, and the reaction system conglomeration of being clamminess, conversion unit can't run well, and degraded and ClCH take place in the easier starch that impels of high temperature simultaneously
2The hydrolysis of COONa causes the decline of substitution value and reaction efficiency.Therefore best temperature of reaction is chosen in 60～70 ℃ and is advisable.
(3), the reaction times is to the influence of substitution value
Be 20% at the massfraction of reaction system water, ClCH
2The COONa add-on be ative starch 8%, NaOH and ClCH
2The COONa mol ratio is 2.5, under 60～70 ℃ of situations about remaining unchanged of etherification temperature, studied the influence of reaction times to substitution value (DS), the results are shown in Table 6;
Table 6 reaction times is to the influence of substitution value:
| Reaction times/h | 2 | 3 | 4 | 5 |
| DS | 0.0984 | 0.114 | 0.118 | 0.115 |
Increase with the etherificate time, increase the duration of contact of each reactant, the carboxymethylation reaction degree improves, but after reaction reached certain hour, reaction tended to balance substantially, along with the continuation prolongation in reaction times, the variation of substitution value is little, with the prolongation in reaction times, the moisture of system product also constantly reduces simultaneously, weighs still both economical with reaction 3h from product moisture control and production efficiency of products.
4, conclusion
In the present invention studies the production test condition and range of selection, the massfraction of water is controlled at 20% in the system, and its each section optimum process is respectively: (1) oxidation stage: the pH value is controlled at 8.5～10.5, oxygenant and ative starch mass ratio are 0.5%, 50 ℃～60 ℃ of oxidizing temperatures, oxidization time 3h; (2) cross-linking stage: the epoxy chloropropane add-on is 0.004% of a starch, and pH value in reaction is 10～11.5, and temperature of reaction is 50～60 ℃, and the reaction times is 1.5h; (3) etherificate stage: ClCH
2The COONa add-on be ative starch 8%, NaOH and ClCH
2The COONa mol ratio is 2.5,60～70 ℃ of etherification temperatures, etherificate time 3h.
