Abstract: 1,145,256. Preparation of copper phthalocyanines. BADISCHE ANILIN- & SODAFABRIK A.G. 24 June, 1966 [25 June, 1965], No. 28370/66. Heading C4P. Copper phthalocyanines are prepared by reacting together at temperatures up to 220‹ C. a phthalodinitrile, e.g. tetrachlorophthalodinitrile; a copper salt, e.g. sulphate, acetate or chloride; an inert solvent, e.g. chlorobenzenes, nitrobenzenes and C 8 , C 9 and C 12 aliphatic alcohols; a nitrogen base, e.g. ammonia and tertiary aromatic bases such as pyridine and quinoline; and as a catalyst material a compound, e.g. an oxide, oxyacid or a salt thereof, a halide or carbonyl compound of an element having an atomic number of 22-24, 26-28, 30, 32-34, or 40-42. A large excess of nitrogen base may replace the solvent.

Abstract: A process for greatly improving the color index of polyhydric alcohols, especially trimethylolpropane, by hydrogenation comprises using, in the hydrogenation, an alcohol which has already been purified by distillation. The catalysts used are those conventionally employed in hydrogenations, preferably copper, nickel, palladium or ruthenium catalysts.

Abstract: A description is given of polyisocyanates of the formula I in which R and R' are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R', and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.

Abstract: The invention relates to a method for producing poly or monomethylol alkanoic acids of general formula (I), wherein R can be the same or different and means a substituted or unsubstituted aliphatic hydrocarbon or a methylol group, from the corresponding poly or monomethylol alkanals of general formula (II), R having the meaning given above, by oxidation with hydrogen peroxide. A differentiation is made between a starting phase and an end phase of the reaction, the reaction temperature selected during the starting phase being lower than that selected during the end phase and being at least >/= 40 DEG C to 85 DEG C, preferably 60 to 80 DEG C, especially preferably 65-75 DEG C, and the temperature during the end phase being > 85 DEG C-110 DEG C, preferably up to 105 DEG C. The method is used especially for producing dimethylol alkanoic acids from the corresponding dimethylol alkanals, especially for producing dimethylol butanal or dimethylol propanal.
