Abstract: 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.

Abstract: The present invention relates to blocked fluorine-containing polyisocyanates which have a fluorine content, calculated as F=19, of 1.0 to 20.0 wt. %, preferably 4.0 to 10.0 wt. %, and are suitable for preparing stoving coatings having a water- and soil-repellent surface, wherein the fluorine-containing polyisocyanates are based on the reaction product of aliphatic polyisocyanates or polyisocyanate mixtures having an NCO content of 10 to 25 wt. % and a functionality of at least 2.5 with monofunctional isocyanate blocking agents and a fluorinated monoalcohols wherein i) 75 to 95 equivalent-% of the isocyanate groups are reacted with isocyanate blocking agents, ii) 5 to 25 equivalent-% of the isocyanate groups are reacted with fluorinated monoalcohols and iii) the equivalents of i) and ii) add up to 100%.

Abstract: A substrate having oil-, water- and soil-repellency and/or soil release properties is produced by treating the substrate with a polyfluoro organic compound having at least 1 urea linkage derived from: (A) at least 1 polyisocyanate which contains at least three isocyanate groups per molecule, (B) at least 1 fluorochemical compound which contains (i) a single functional group having 1 or more Zerewitinoff hydrogen atom S and (ii) at least 2 carbon atoms each of which contains at least 2 fluorine atoms, and (C) sufficient water to react with from about 5% to about 60% of the isocyanate groups.

Abstract: The invention relates to a process for the preparation of known .beta.-halogeno-tert.-alkyl isocyanates of the formula ##STR1## in which X represents chlorine,Y represents hydrogen or chlorine,R.sub.1 represents in each case straight-chain or branched alkyl or halogenoalkyl andR.sub.2 represents in each case straight-chain or branched alkyl, halogenoalkyl or optionally halogen- and/or trifluoromethyl-substituted phenyl,where tert.-alkyl isocyanates of the formula (II) ##STR2## in which R.sub.1 and R.sub.2 have the meaning given above,are converted to the corresponding tert.-alkylcarbamoyl chlorides by means of hydrogen chloride gas, these are reacted with elemental chlorine under irradiation or in the presence of catalysts, and finally the .beta.-halogeno-tert.-alkyl isocyanates are liberated by dehydrohalogenation at elevated temperature.

Abstract: The invention relates to a new process for the preparation of known .beta.-halogeno-tert.-alkyl isocyanates of the formula ##STR1## in which X represents chlorine,Y represents hydrogen or chlorine,R.sup.1 represents in each case straight-chain or branched alkyl or halogeno alkyl andR.sup.2 represents in each case straight-chain or branched alkyl or halogeno alkyl or optionally halogen-and/or trifluoromethyl-substituted phenyl,where tert.-alkyl isocyanates of the formula (II) ##STR2## are reacted with chlorine, optionally under irradiation or in the presence of catalysts, in a suitable apparatus.

Abstract: Closely boiling diastereomeric isomer alcohols are separated by converting them to esters having disparate boiling points, separating the ester isomers by distillation and saponifying the separate ester isomers to obtain the individual alcohol isomers.

Abstract: Chloro-aromatic compounds of the formula ##STR1## wherein R is CF.sub.3, OCF.sub.3, OC.sub.2 F.sub.5, CN, NCO, or COCl, m is 0, 1 or 2; n is 0, 1 or 2; q is 1 or 2; q+m+n is less than 6; and when q is 1, m is 2; are prepared by the vapor phase chloro-denitration reaction of a chlorinating agent with a nitro-aromatic compound of the formula ##STR2## where R, m, n and q are as defined above.

Abstract: A process for the stimulaneous halogenation and fluorination of aromatic derivatives substituted by at least one group containing a halogenoalkyl unit. The aromatic derivative is reacted with the halogen in liquid hydrofluoric acid. The products obtained are useful as intermediates for the synthesis of compounds having a plant-protecting or pharmaceutical activity.
