Abstract
The invention discloses a method for directly producing a disproportionated rosin potassium soap with the solid content of 25 percent, and relates to the technical field of deep processing of chemical rosin. The method comprises the following steps of: adding 20 to 23 percent of flaky or granular disproportionated rosin by weight and 67 to 75 percent of potassium hydroxide solution by weight at the same time into a saponification reaction kettle containing 5 to 10 percent of soft water by weight, mixing, stirring, and cooling to obtain the disproportionated rosin potassium soap after the saponification reaction stops, wherein the saponification reaction temperature is 50 to 100 DEG C, the saponification reaction time is 30 to 120 minutes, and the concentration of the potassium hydroxide solution is 4.5 to 5.5 percent. Compared with the prior art, the method disclosed by the invention has the advantage that the problems of complicated production processes, high cost and energy waste of the conventional disproportionated rosin potassium soap with the solid content of 25 percent can be solved.
Description
Technical field
The present invention relates to chemical industry rosin deep process technology field, especially a kind of method of direct production solid content 25% disproportionated rosin potassium soap.
Background technology
Nilox resin is a kind of by one of Abietyl modified main deep processed product that forms, that abietic type acid in the rosin is under the effect of catalyzer, under the certain temperature condition, becoming dehydrogenation abietic acid, dihydroabietic acid or tetrahydroabietic acid by double-bond rearrangement is main resinous acid mixture, make modified product oxygen uptake activity decreased, character is more stable.In actual applications, the form of sylvite mainly with it is used.
When using nilox resin to make the emulsifying agent of the polymer letex polymerization such as styrene-butadiene rubber(SBR), generally make first disproportionated rosin potassium soap.Namely take nilox resin as raw material, add potassium hydroxide aqueous solution, carry out saponification reaction, the disproportionated rosin potassium soap of preparation solid weight mark 80%.Present domestic disproportionated rosin potassium soap manufacturing enterprise produces solid content 60%, 80% paste of soap product, and the production transparency is good, look is number shallow, the enterprise of the solid content 25% disproportionated rosin potassium soap aqueous solution that cloud point is low, much be buy solid content 60%, 80% disproportionated rosin potassium soap product dilutes and obtains solid content 25% disproportionated rosin potassium soap.Like this in whole solid content 25% disproportionated rosin potassium soap production process, increase the disproportionated rosin potassium soap cooling of solid content 80%, reheated the process of dilution, wasted the energy, for disproportionated rosin potassium soap manufacturing enterprise, production process and production cost have also been increased.
Summary of the invention
The invention provides a kind of method of direct production solid content 25% disproportionated rosin potassium soap, complicated with the production process that solves existing solid content 25% disproportionated rosin potassium soap, cost is high, the problem that wastes energy.
In order to address the above problem, technical scheme of the present invention is: may further comprise the steps: in the saponification reaction still of the soft water that contains 5%～10% weight, the sheet or granular nilox resin and the potassium hydroxide solution mix and blend of 67%～75% weight that add simultaneously 20%～23% weight, after saponification reaction stops, namely getting disproportionated rosin sodium soap after the cooling; The temperature of described saponification reaction is 50 ° of C～100 ° C; The time of described saponification reaction is 30 minutes～120 minutes; The concentration of described potassium hydroxide solution is 4.5%～5.5%.。
In the technique scheme, more specifically scheme can be: the temperature of described saponification reaction is 80 ° of C; The concentration of described potassium hydroxide solution is 5.0%.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
Present method adopts nilox resin and potassium hydroxide solution to carry out saponification reaction, the disproportionated rosin potassium soap of direct production solid content 25%, and by the concentration of control potassium hydroxide solution, the saponification reaction time is controlled the index of product; Present method can also be made first the disproportionated rosin potassium soap of solid content 80%, again the disproportionated rosin potassium soap heating of solid content 80% is diluted to the disproportionated rosin potassium soap of solid content 25%, but directly carry out saponification reaction with sheet or granular nilox resin and potassium hydroxide solution and get, saved the energy, reduce manufacturing procedure, reduced the production cost of enterprise.
