Note    (1), Do not use in personal care products.
(2), Do not use in nitrosating environment. Reaction of 2-propen-1-amine and nitrous acid can not produce nitrosamines, however, reaction of contained secondary amine of 2-propen-1-amine and nitrous acid can produce nitrosamines. Nitrosamine is a carcinogen.
Synthesis
Currently, sulfated reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfates.
Generally, C10-16 alkyl alcohol and sulfur trioxide react through reactor, then 2-propen-1-amine neutralizes, 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.
