| titleOfInvention | A kind of method of oil analysis conversion regulation Sodium guanylate crystallization process |
| abstract | A kind of method that the present invention discloses oil analysis conversion regulation Sodium guanylate crystallization process, includes the following steps: step 1: in the Sodium guanylate aqueous solution of pH9.5-10.0, isopropanol is added as anti-solvent, making mixed solution is in oily state；Step 2: into mixed solution obtained by step 1, addition Sodium guanylate I type crystal is as crystal seed, and the Sodium guanylate aqueous solution that pH7.0-7.7 is then slowly added dropwise turns crystalline substance, and system temperature is controlled at 20-40 DEG C, and stirring intensity is between 150-400rpm；Step 3: the mixed solution of isopropanol and hydrochloric acid being added dropwise into step 2 acquired solution, and the processing that cools down is filtered with improving product yield, and drying obtains product.Crystallization mode of the present invention is easy to operate reproducible, and the Sodium guanylate I type crystal product of homogeneous grain diameter can be obtained, and can be effectively improved isopropanol as dissolved agent is existing and turn the problems such as brilliant difficult, yield is low. |
