A kind of method for preparing the propyl alcohol of 2 amino, 2 methyl 1

The present invention relates to a kind of method for preparing the propyl alcohol of 2 amino, 2 methyl 1, comprise the following steps：1) 2 chloropropanes and Cymag reaction 2 methyl propionitrile of generation；2) the aldol reaction generation hydroxypropionitrile of 2,2 dimethyl 3 occurs for 2 methyl propionitrile and formaldehyde；3) the hydrolysis generation hydroxypropanamide of 2,2 dimethyl 3 occurs for the hydroxypropionitrile of 2,2 dimethyl 3；4) propyl alcohol of 2 methyl of hoffman degradation reaction 2 amino of generation 1 occurs for the hydroxypropanamide of 2,2 dimethyl 3.Each step raw material of this method is cheap and easy to get, and reaction process is simple, without harsh reaction condition, and substantially, yield is high for cost advantage, pollutes low, product is easily purified.
