O que \u00e9 toluhidroquinona \/ 2-metil-hidroquinona?<\/strong><\/h2>\n

1. \u00c9 um cristal branco ou quase branco, que pode ser sublimado pelo calor e se tornar preto quando molhado.<\/span> Pouco sol\u00favel em \u00e1gua, sol\u00favel em \u00e9ster et\u00edlico, metanol e insol\u00favel em \u00e9ter de petr\u00f3leo. \u00c9 um importante intermedi\u00e1rio para a s\u00edntese industrial de vitamina E.<\/span><\/h4>\n

2. Um novo tipo de inibidor de polimeriza\u00e7\u00e3o, a toluhidroquinona, \u00e9 um tipo eficiente de inibidor de polimeriza\u00e7\u00e3o de resina insaturada. Em geral, a adi\u00e7\u00e3o de dois d\u00e9cimos de mil\u00e9simo da resina pode exercer um bom efeito de inibi\u00e7\u00e3o da polimeriza\u00e7\u00e3o na produ\u00e7\u00e3o e no armazenamento, al\u00e9m de impedir que a resina endure\u00e7a ap\u00f3s a polimeriza\u00e7\u00e3o. A estabilidade \u00e9 de mais de meio ano; a toluhidroquinona tem boa solubilidade e n\u00e3o polui seus produtos. N\u00e3o \u00e9 afetada pela temperatura e pelo ambiente. \u00c9 necess\u00e1rio apenas um produto para garantir a qualidade da resina.<\/h4>\n

3. A toluhidroquinona n\u00e3o \u00e9 afetada pela temperatura e sempre reage rapidamente com os radicais livres para obter uma r\u00e1pida inibi\u00e7\u00e3o da polimeriza\u00e7\u00e3o, enquanto o terc-butilcatecol perder\u00e1 o efeito de inibi\u00e7\u00e3o da polimeriza\u00e7\u00e3o e at\u00e9 mesmo afetar\u00e1 a cor da resina ap\u00f3s a decomposi\u00e7\u00e3o t\u00e9rmica; ela n\u00e3o \u00e9 afetada pelo ambiente, em um recipiente aer\u00f3bico ou livre de oxig\u00eanio, pode inibir a polimeriza\u00e7\u00e3o, enquanto a hidroquinona n\u00e3o funciona em um recipiente com defici\u00eancia de oxig\u00eanio.<\/h4>\n

4. A resina produzida com o uso da toluidroquinona n\u00e3o afetar\u00e1 a velocidade final de cura da resina sob a a\u00e7\u00e3o do sistema de inicia\u00e7\u00e3o; a toluidroquinona pode apresentar um excelente efeito de inibi\u00e7\u00e3o da polimeriza\u00e7\u00e3o nas resinas de extrus\u00e3o e pultrus\u00e3o do tipo de cura em alta temperatura, o que \u00e9 um novo produto de uma gera\u00e7\u00e3o de inibidores de polimeriza\u00e7\u00e3o de resinas insaturadas.<\/h4>\n

 <\/p>\n

Tolu-hidroquinona \/ 2-Metil-hidroquinona<\/strong>Uso<\/strong><\/h2>\n

1. 2-Metilhidroquinona \/ Toluhidroquinona \u00e9 um importante intermedi\u00e1rio na s\u00edntese industrial da vitamina E e pode ser obtido por rea\u00e7\u00e3o de condensa\u00e7\u00e3o com a cadeia lateral do isofitol.<\/span><\/h4>\n

2. Com a 2-metil-hidroquinona\/tolu-hidroquinona como anel principal e a cadeia lateral C isofitol sob a condi\u00e7\u00e3o de \u00e1cido sulf\u00farico como agente de condensa\u00e7\u00e3o, a vitamina pode ser obtida por aquecimento e condensa\u00e7\u00e3o em acetato de etila.<\/span> Nos \u00faltimos anos, devido \u00e0 ampla aplica\u00e7\u00e3o da vitamina E nas \u00e1reas m\u00e9dica, aliment\u00edcia e de ra\u00e7\u00f5es, os produtos com vitamina E continuaram a ser populares em todo o mundo, especialmente nos mercados europeu e americano.<\/span><\/h4>\n

3. 2-Metilhidroquinona\/Toluhidroquinona tamb\u00e9m \u00e9 um novo tipo de inibidor de polimeriza\u00e7\u00e3o.<\/h4>\n

4. Esse produto pode ser usado como antioxidante. Quando existem radicais livres, eles podem reagir com os radicais livres para consumir os radicais livres.<\/h4>\n
