(2), Do not use in nitrosating environment. Reaction of secondary amine and nitrous acid can produce nitrosamines. Nitrosamine is a carcinogen.
Currently, sulfated reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfates.
Generally, lauryl alcohol and sulfur trioxide react through reactor, then mixed isopropanolamines neutralize, finally obtain product.
US patent 8,921,588 (Process for preparing sulfates and/or sulfonates in a micro-reaction system) presents a synthetic process. Conditions: mole ratio of sulfur trioxide and alcohols or other raw materials: 1:1; temperature: 30-60°C; reactor: falling film reactor.
