style="text-indent:25px">一種1,2-丙二胺，采用異丙醇胺、氨在加氫和加催化劑的條件下反應(yīng)制備1,2-丙二胺，將一定量的異丙醇胺、催化劑加入到1升壓力反應(yīng)釜中，用氮?dú)庵脫Q壓力反應(yīng)釜中空氣三次，然后加入氨，攪拌下加熱并通入氫氣到8-12MPa，且用氫氣保持該壓力，反應(yīng)4-5小時后，結(jié)束反應(yīng)，得1,2-丙二胺成品。本工藝是是一條清潔化生產(chǎn)工藝，產(chǎn)品收率、含量高，原料成本低，催化劑可以循環(huán)套用。在一臺套壓力釜中就可以完成合成反應(yīng)，然后經(jīng)精餾塔精餾獲得產(chǎn)品，減少了設(shè)備投資，簡化了生產(chǎn)工藝。1，2丙二胺防護(hù)：戴橡膠耐油手套。江蘇巴斯夫1-2丙二胺廠</p><p
