    摘要： COMPOUNDS OF THE GENERAL FORMULA

    R1-CH(-X)-CH2-CH2-O-(CNH2NO-)M-R2

    WHEREIN R1 STANDS FOR ALKYL CONTAINING 4 TO 20 CARBON ATOMS, X STANDS FOR CHLORINE OR BROMINE, R2 STAND FOR ALKYL CONTAINING 1 TO 20 CARBON ATOMS, A RADICAL OF AN ALKANE-CARBOXYLIC ACID CONTAINING 1 TO 18 CARBON ATOMS, THE PHENYL RADICAL, THE NAPHTHYL RADICAL OR AN ALKYL-PHENYL RADICAL CONTAINING 1 TO 12 ALIPHATIC CARBON ATOMS, THE BENZOYL OR BENZYL RADICAL OR THE RADICAL

    R1-CH(-X)-CH2-CH2-

    N STANDS FOR AN INTEGER FROM 2 TO 4 AND M STANDS FOR AN INTEGER FROM 2 TO 200, WHICH ARE USEFUL AS TENSIDES AND EMULSIFIERS, AND A PROCESS FOR PREPARING THEM BY REACTING A HALOGENO-METHYL ETHER OF THE FORMULA

    R3O(CNH2NO)M-CH2X

    IN WHICH X, N AND M HAVE THE MEANINGS GIVEN ABOVE, AND R3 STANDS FOR THE RADICAL -CH2CL OR -CH2BR OR HAS THE SAME MEANING AS R2, IN THE PRESENCE OF A FRIEDEL-CRAFTS CATALYST, AT 10 TO 100*C., WITH AN A-OLEFIN CONTAINING 8 TO 20 CARBON ATOMS.

    摘要： Dispersions of pigments, disperse- or vat-dyestuffs, wherein the dispersing agent is formed either by co-condensation of a phenolic component, formaldehyde and an alkali metal sulfite or of a sulfonated phenolic component and formaldehyde. These dispersions are characterized in that the dispersing agent used shows an improved dispersing effect. Furthermore, they can also be used when being neutralized for the dispersing alkali sensitive dyestuffs and they show no tendency to soil the fabrics so that also clean shades may be dyed.

    摘要： Polyfunctional alcohols with at least two alcoholic hydroxy groups are effective agents for dispelling fog and clouds. Preferred solid compounds are the so called sugar alcohols, saccharides and polyvinyl-alcohol, as liquid compounds or compounds with a low melting point alkane-diols, -triols or polyols or their reaction products with oxalkylating agents. The said compounds are sprayed into fog or clouds in finely dispersed form. They may be used, optionally together with other fog and clouds dispelling agents.
