    摘要: A process for providing methylene-bridged polyphenyl polyamines from aniline and formaldehyde according to the invention comprises the subsequent steps of a) condensing aniline and formaldehyde, providing a condensate, the molar ratio of aniline to formaldehyde being chosen in the range of 2 to 3.5; b) reacting, in a first catalytic reaction step, at a reaction temperature within the range of about 30°C to about 100°C, said condensate over a solid catalyst being chosen from the group consisting of clays, silicates, silica-aluminas and ion exchange resins, whereby an intermediate mixture is provided, the intermediate mixture comprising amino benzyl amines; c) converting, in a subsequent catalytic reaction step, at a temperature within the range of about 70°C to about 250°C, the reaction temperature in said subsequent catalytic reaction step is higher than the reaction temperature in said first catalytic reaction step, said intermediate mixture into methylene-bridged polyphenyl polyamines in presence of a subsequent solid catalyst being chosen from the group consisting of zeolites, delaminated zeolites and ordered mesoporous materials, thereby providing said methylene-bridged polyphenyl polyamines.

    摘要: The present invention relates to a process for manufacturing isocyanates from an amine compound. The process comprises the steps of a) Providing chlorine; b) Providing carbon monoxide; c) Reacting said chlorine and said carbon monoxide for providing phosgene, the carbon monoxide being provided in an adjustable molar excess; d) Providing an amine compound and phosgenating said amine compound using said phosgene thereby providing said isocyanate; the process further comprises adjusting said adjustable molar excess, i.e. the molar excess of carbon monoxide, for adjusting the color of the isocyanate.

    摘要: The present invention relates to a vegetable oil based autocatalytic polyol derived from the reaction product of an epoxidized vegetable oil and an alkanolamine. The autocatalytic polyol according to the present invention may be used as a replacement for all or a portion of petroleum derived polyols generally used in the production of polyurethane materials. The polyurethane materials produced may be used in a variety of applications, such as, foam, elastomer and coating applications.
