3，4-二甲基吡唑磷酸盐的合成

摘要

3,4-dimethylpyrazole phosphate was is synthesized from butanone and paraformaldehyde by condensation, eyelization, dehydrogenation, salification with a purity of 99.2% and an overall yield of 89.6%.The process is simple, low cost, high yield and suitable for industrial production.%以丁酮、多聚甲醛为原料，通过缩合经缩合、环合、脱氢、成盐四步反应来制备3,4-二甲基吡唑磷酸盐，含量99．2％，总收率89．6％。该工艺简便、生产成本低、收率高且适合工业化生产。
