  • Patent number: 3989692
    Abstract: Phthalocyanine reactive dyestuffs of the formula ##SPC1##Wherein Pc, R.sub.1, R.sub.2, R.sub.3 -R.sub.5, a, b and c and Z have the meaning given in the description. They are outstandingly suitable for dyeing and printing materials containing cellulose, such as natural and regenerated cellulose, in accordance with the techniques known for the purpose. The new dyestuffs are also suitable for dyeing materials containing amide groups, such as wool, silk and synthetic polyamides. Dyeings obtained on textile cellulose, in particular, distinguish themselves by very good fastness properties, especially fastness to light and to wet processing.

  • Patent number: 3988310
    Abstract: The invention relates to valuable new reactive dyestuffs of the general formula ##SPC1##In which A stands for hydrogen, a methyl, phenyl, lower carbalkoxy, optionally substituted carboxamide or a carboxy group; B denotes a carboxy, lower carbalkoxy, optionally substituted carboxamide or nitrile group; Z means a hydroxy or amino group; R.sub.1 and R.sub.2 stand for identical or different radicals such as hydrogen or methyl; D denotes the radical of a diazo component containing a reactive group; and n means the number 0 or 1; which are suitable for the dyeing and printing of materials containing hydroxyl or amide groups and for dyeing natural or regenerated cellulose fast to washing.

  • Patent number: 3979469
    Abstract: New polyfluoroalkyl iodides of the formula ##EQU1## are provided, wherein R.sub.f represents a fluorinated hydrocarbon radical with 3 to 18 carbon atoms, R.sub.1 represents hydrogen or fluorine, R.sub.3 and R.sub.4 each independently represents hydrogen, lower alkyl, hydroxyalkyl, carboxy, carbalkoxy, --(CH.sub.2).sub.p OCOR.sub.2, in which R.sub.2 represents hydrogen or alkyl with 1 to 3 carbon atoms and p is 0 or a whole number from 1 to 3, phenyl and alkylphenyl, or R.sub.3 and R.sub.4 together with the carbon atoms to which they are bonded represent an optionally substituted cycloaliphatic radical with 5 or 6 ring carbon atoms, and n is a whole number from 1 to 3.The new compounds are useful as intermediates for the manufacture of oil- and water-repellents, as oil- and water-repellents per se, as lubricants and as surface active assistants.

  • Patent number: 3970669
    Abstract: The present invention provides new perfluoroalkylcarboxylic acid esters of the formula ##EQU1## WHEREIN R.sub.f is perfluoroalkyl with 4 to 18 carbon atoms, A represents a radical forming with the --NCO--N-group ethylene urea, hydantoin or isocyanurate radicals, B is --O-- or --OH Cl-- , m is a whole number from 1 to 3, q is 1 or 2 and x is 0, 1 or 2, with x being 0 or 1 if m is 1. The new compounds are useful for producing oil and water-repellent finishes on porous and non-porous finishes, such as paper, textiles or plastics.

  • Patent number: 3954817
    Abstract: A new process for the manufacture of perfluoroalkylmethylenecarboxylic acids of the formulaR.sub.f (CH.sub.2 CF.sub.2).sub.m.sub.-1 CH.sub.2 COOH,wherein R.sub.f is an unbranched or branched perfluoroalkyl radical with 3 to 14 carbon atoms and m is 1 to 3, which comprises reacting perfluoroalkyl iodides of the formula R.sub.f (CH.sub.2 CF.sub.2).sub.m -I with concentrated nitric acid. The compounds are e.g. useful as intermediates for the manufacture of oil- and water repellents; further they can be used themselves e.g. as surface active assistants or as lubricants.
