Synthesis and application of alcohol amine with expended main carbon chain

A method for synthesizing a novel alcohol amine (NAA) with an extended main carbon chain, comprising the following steps:

• adding a tertiary amine (R—OH) and a catalyst of concentrated sulfuric acid into a reaction vessel to mix uniformly, then adding hydrobromic acid and heating to 80° C.-110° C. for reacting, cooling and distilling to obtain bromoethanolamine after the reacting for 30-60 minutes, wherein a molar ratio of hydrobromic acid to tertiary amine is 1:1;
• adding a cyanating agent and the catalyst into the distilled solution, and reacting for 50-80 minutes at a temperature of 110° C.-240° C. to obtain cyanoethanolamine;
• after obtaining the cyanoethanolamine, adding an 70%-80% sulfuric acid aqueous solution, heating and hydrolyzing to obtain carboxylolamine;
• and
• adding a reducing agent and refluxing, reducing the carboxylolamine to obtain an alcohol amine with an extended main carbon chain;
• the reaction scheme for synthesizing the novel alcohol amine (NAA) with an extended main carbon chain is as follows:
• in the reaction scheme, the compound 1 is the tertiary amine (R—OH), the compound 2 is the bromoethanolamine, the compound 3 is the cyanoethanolamine, the compound 4 is the carboxylolamine and the NAA is the novel alcohol amine (NAA) with an extended main carbon chain.
