| 摘 要：介紹了殺蟲(chóng)單的介質(zhì)法磺化反應及結晶工藝的研究 ,探討了影響磺化收率和殺蟲(chóng)單粉劑含量及出粉率的主要因素 ,找出了生產(chǎn)高純度殺蟲(chóng)單粉劑的最優(yōu)工藝條件。實(shí)驗結果表明 :以含量為 50 %的氯化物鹽酸鹽為原料 ,按質(zhì)量比為 1:0 .95比例加入濃度為 85%的甲醇介質(zhì)進(jìn)行磺化反慶 ,磺化收率可達 88%以上 ,生產(chǎn)的殺蟲(chóng)單含量≥ 95% ,折 10 0 %計的殺蟲(chóng)單出粉率≥ 4 6 % ,折 10 0 %殺蟲(chóng)單粉劑耗甲醇≤ 0 ,17t/t |

| Abstract：The sulphonation reaction in media and the crystallization process in shachongdan production have been emphasisly discussed. The main influence factors yn sulphonation and crystallization process has been investigated and the optimum conditions of process have been foudn.The conclusions show that: By taking the chloride hydrochloric salt of 50% in content as raw material,adding methanol of 85% in concentration to the reaction system according to the mass ratio as 1∶0.95, the sulphonation recovery is over 88... |
