Apresenta\u00e7\u00e3o<\/strong><\/span><\/p>

O \u00c1lcool Met\u00edlico (Metanol) \u00e9 um l\u00edquido claro, incolor, vol\u00e1til, altamente polar com um odor caracter\u00edstico. \u00c9 misc\u00edvel em \u00e1gua, \u00e1lcool e \u00e9ter. \u00c9 uma das mat\u00e9rias-primas b\u00e1sicas na ind\u00fastria da qu\u00edmica org\u00e2nica.<\/span><\/p>

O Metanol apresenta rea\u00e7\u00f5es t\u00edpicas de \u00e1lcoois alif\u00e1ticos.<\/span><\/p>

Os maiores usos do Metanol s\u00e3o na produ\u00e7\u00e3o de formalde\u00eddo e biodiesel.<\/span><\/p>

O Metanol tamb\u00e9m \u00e9 bastante utilizado como mat\u00e9ria-prima para a produ\u00e7\u00e3o de Metilmetacrilato (MMA), Metilacrilato (MA) e Metilaminas.<\/span><\/p>

\u00c9 usado como solvente, em grande parte, devido a sua miscibilidade com a maioria dos solventes org\u00e2nicos. Solu\u00e7\u00f5es de l\u00e1tices e resinas em Metanol usualmente t\u00eam menor viscosidade do que seria poss\u00edvel com outros \u00e1lcoois.<\/span><\/p>

Este \u00e1lcool \u00e9 um excelente combust\u00edvel para motores alternativos de alta compress\u00e3o, bem como um dos combust\u00edveis usados em avi\u00f5es a jatos e foguetes.<\/span><\/p>
