Zusammenfassung: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.
