CAS: 375-96-2; Perfluorononane

该化合物是一种全氟化合物,其特点是由9个碳原子组成的链条,每个原子都完全饱和氟化,成为全氟烷系的一部分.其化学配方为C9F20,表明典型烷中的所有氢原子已被氟烃所取代.这种替代具有独特的特性,如高热稳定性,低表面紧张度和极好的化学惰性,使全氟内烷耐降解和反应过程的阻力.它是室内温度低色,无味液体,且具有低挥发性.由于其疏水和疏脂性质,它不与水混合,而且经常用于需要非粉末或水性特性的应用中.然而,全氟内烷与其他全氟化合物一样,因其在环境中的持久性和潜在生物累积性而引起环境和健康问题.对于其使用和处置,监管性审查正在增加,因为它可能对环境污染和人类健康造成风险.

    摘要:A one-pot process for the synthesis of isocyanates, polyisocyanates or mixtures thereof which includes the steps of:n i. preparing a mixture comprising an amine, an alcohol, an oxygen-containing gas, carbon monoxide, a metal complex catalyst selected from the group consisting of macrocyclic complex catalysts and cobalt Shiff base catalysts; and a solvent selected from the group consisting of aliphatic or aromatic halocarbons, perhalogenated alcohols, halogenated ethers, halogenated ketones, perfluorinated hydrocarbons, polymers of chlorotrifluoroethylene having the formula —(CF 2 —CFCl) n wherein n is between 2 and 10, and mixtures thereof; ii. subjecting the resulting mixture to a first heating under pressure; iii. cooling and depressurizing the mixture resulting from the previous step; and iv. subjecting the mixture of the previous step to a second heating to separate out the isocyanate product from the mixture.
