O TBC tem boa compatibilidade com resina de vinil, acetilbutirato de celulose, acetato de celulose, benzilcelulose, etilcelulose, etc., e \u00e9 um bom plastificante com melhor efici\u00eancia de plastifica\u00e7\u00e3o. Plastificante; o TBC tamb\u00e9m tem as caracter\u00edsticas de antibacteriano sem crescimento de bact\u00e9rias, n\u00e3o irritante, retardador de chamas e degrad\u00e1vel.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">M\u00e9todo de prepara\u00e7\u00e3o do TBC<\/h2>\r\n\r\n\r\n\r\n<p>O \u00e1cido c\u00edtrico e o n-butanol reagem na presen\u00e7a de um catalisador e de um agente transportador de \u00e1gua para gerar o citrato de tributil, e o produto \u00e9 obtido por meio de processos como desalcooliza\u00e7\u00e3o, neutraliza\u00e7\u00e3o, lavagem com \u00e1gua, decapagem a vapor, descolora\u00e7\u00e3o e filtro-prensa.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Princ\u00edpio da rea\u00e7\u00e3o TBC<\/h2>\r\n\r\n\r\n\r\n<p>O citrato de tributila pode ser sintetizado pela rea\u00e7\u00e3o de esterifica\u00e7\u00e3o do \u00e1cido c\u00edtrico e do n-butanol. Os catalisadores de esterifica\u00e7\u00e3o tradicionais s\u00e3o \u00e1cidos fortes, como o \u00e1cido sulf\u00farico e o \u00e1cido benzenossulf\u00f4nico, que t\u00eam pre\u00e7o baixo e alta atividade catal\u00edtica, mas apresentam muitas rea\u00e7\u00f5es colaterais, p\u00f3s-processamento complicado, corros\u00e3o severa do equipamento e emiss\u00f5es de \u00e1cido residual que poluem seriamente o meio ambiente. Portanto, a s\u00edntese n\u00e3o catalisada por \u00e1cido de produtos de \u00e9ster tem sido uma meta de pesquisa de longo prazo. H\u00e1 muitos estudos sobre \u00e1cido heteropoli\u00e1cido com suporte de carbono ativado, resina de troca cati\u00f4nica e cloreto de terras raras misto. No entanto, os m\u00e9todos acima t\u00eam muitas etapas de processo de p\u00f3s-tratamento, que n\u00e3o s\u00e3o f\u00e1ceis de controlar, e o processo de prepara\u00e7\u00e3o do catalisador \u00e9 complicado, o que n\u00e3o favorece a aplica\u00e7\u00e3o e a promo\u00e7\u00e3o.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Uso TBC<\/h2>\r\n\r\n\r\n\r\n<p>Esse produto \u00e9 sol\u00favel na maioria dos solventes org\u00e2nicos. Ele tem as caracter\u00edsticas de baixa volatilidade, boa compatibilidade com a resina e alta efici\u00eancia de plastifica\u00e7\u00e3o. Portanto, seu uso \u00e9 permitido na produ\u00e7\u00e3o de embalagens de alimentos e produtos m\u00e9dicos e sanit\u00e1rios em v\u00e1rios pa\u00edses do mundo, bem como em brinquedos macios para crian\u00e7as, produtos farmac\u00eauticos, produtos m\u00e9dicos, sabores e fragr\u00e2ncias. A produ\u00e7\u00e3o de cosm\u00e9ticos e outros setores.<\/p>\r\n\r\n\r\n\r\n<p>O TBC pode conferir aos produtos boa resist\u00eancia ao frio, \u00e0 \u00e1gua e ao mofo. A resina apresenta boa transpar\u00eancia e desempenho de flex\u00e3o em baixa temperatura ap\u00f3s ser plastificada com esse produto, al\u00e9m de ter baixa volatilidade e baixa extratibilidade em diferentes meios, boa estabilidade t\u00e9rmica e n\u00e3o mudar de cor quando exposta ao calor. O \u00f3leo lubrificante feito com TBC tem boas propriedades lubrificantes.<\/p>\r\n\r\n\r\n\r\n<p>Nos \u00faltimos anos, os principais plastificantes usados com frequ\u00eancia na ind\u00fastria s\u00e3o os plastificantes de ftalato. Como os plastificantes de ftalato podem induzir \u00e0 carcinog\u00eanese, os pa\u00edses estrangeiros controlaram rigorosamente seu uso, e meu pa\u00eds tamb\u00e9m formulou leis e regulamenta\u00e7\u00f5es relevantes que eliminar\u00e3o gradualmente seu uso em materiais de embalagem de alimentos, equipamentos m\u00e9dicos e brinquedos. O citrato de tributila (TBC) \u00e9 um novo tipo de plastificante n\u00e3o t\u00f3xico para pl\u00e1sticos. Ele atraiu grande aten\u00e7\u00e3o devido \u00e0 sua boa compatibilidade, alta efici\u00eancia de plastifica\u00e7\u00e3o, n\u00e3o t\u00f3xico, n\u00e3o vol\u00e1til e forte resist\u00eancia a intemp\u00e9ries. Ele se tornou a primeira op\u00e7\u00e3o para substituir o o-benzeno. Produtos de prote\u00e7\u00e3o ambiental verde de diformato.<\/p>\r\n\r\n\r\n\r\n<p>Com o aumento da conscientiza\u00e7\u00e3o das pessoas sobre a prote\u00e7\u00e3o ambiental e o aprimoramento das leis e regulamenta\u00e7\u00f5es de prote\u00e7\u00e3o ambiental, o desenvolvimento e a produ\u00e7\u00e3o de citrato de tributila t\u00eam excelentes perspectivas de desenvolvimento.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Plastificantes retardantes de chama da mesma s\u00e9rie<\/strong><\/h2>\r\n<table style=\"border-collapse: collapse;
