It is used in a variety of industrial applications including the production of resins, pharmaceuticals and cosmetics.  It is also used as a corrosion inhibitor and defoamer.  <\/span><\/p>\n<p><span style=\"font-size: 14pt\">DMEA can be synthesized by reacting acetaldehyde with ammonia and formaldehyde.  The reaction is carried out in the presence of a catalyst such as hydrochloric acid.  The reaction is exothermic and the product is a mixture of DMEA and 2-methylaminoethanol (MEA).  MEA can be separated from DMEA by distillation.  <\/span><\/p>\n<p><span style=\"font-size: 14pt\">The following is the chemical formula for the synthesis of DMEA:<\/span><\/p>\n<p><span style=\"font-size: 14pt\">CH3CHO + NH3 + CH2O -&gt; (CH3)2NCH2CH2OH<\/span><br \/>\n <span style=\"font-size: 14pt\">DMEA can also be synthesized by the reaction of ethylamine and formaldehyde.  The reaction is carried out in the presence of a catalyst such as hydrochloric acid.  The reaction is exothermic and the product is a mixture of DMEA and ethanolamine (EA).  EA can be separated from DMEA by distillation.  <\/span><\/p>\n<p><span style=\"font-size: 14pt\">This is the chemical equation for the synthesis of DMEA from ethylamine:<\/span><\/p>\n<p><span style=\"font-size: 14pt\">CH3CH2NH2 + CH2O -&gt; (CH3)2NCH2CH2OH<\/span><br \/>\n <span style=\"font-size: 14pt\">DMEA is a hazardous substance.  It is flammable and irritating to skin and eyes.  It is also a potential carcinogen.  <\/span><\/p>\n<p><span style=\"font-size: 14pt\">DMEA should be stored in a cool, dry place.  Keep away from heat, sparks and open flames.  Dispose of in accordance with local regulations.  <\/span><\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>N,N-Dimethylethanolamine (DMEA) is a colorless liquid w&#8230;<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[14597],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/42847"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=42847"}],"version-history":[{"count":0,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/42847\/revisions"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=42847"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=42847"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=42847"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
