【摘要】 将含三氯乙醛废硫酸加水稀释后，不需预热，直接向废硫酸中通入水蒸汽进行蒸馏的方法处理含三氯乙醛废硫酸。处理后，成品硫酸中含硫酸６５～７０％，三氯乙醛、三氯乙酸含量＜２０ｐｐｍ，并得到硫酸酯，成品硫酸可用于制造硫酸盐类更多还原

【Abstract】 The waste sulfuric acid containing chloral was treated with new process,including diluted with water and directly steam distillating without pre-heating.The resulted sulfuric acid is in content of 65～70%,chloral and trichloracetic acid<20 ppm,and can be used to produce sulfate.With this process,the sulfuric ester was also obtained.更多还原
