一、工艺简介

1、磺化

 将定量的工业萘倒入3000L磺化反应釜内，在密闭状态下向反应釜夹套内通入194℃的蒸汽，将萘融化，当熔萘温度升到135℃时，停止加热，开始向反应釜内滴加硫酸（98%）。硫酸溶于水放出大量热，可使水沸腾，为防止反应釜温度过高，稀释硫酸时应通过滴加方式进料，同时不断搅拌，应控制滴加时间在0.5~1小时内。硫酸滴加完毕后，开始供气加热，使物料温度上升到160~165℃，此时硫酸与工业萘开始进行磺化反应，生成α-萘磺酸与β-萘磺酸。为保证磺化反应顺利进行，控制反应温度在160℃~165℃之间，为此要不断调整供气压力。为使萘尽可能完全磺化，应使硫酸过量10%，通过控制物料酸度值来实现，控制其酸度值在3.1~3.3之间。磺化反应阶段一般需2小时。 磺化反应结束后，向反应釜内通入蒸气，直接将萘磺酸压入水解釜内。反应过程需补充部分稀释水，来调节物料粘度。
