    摘要： A process for producing particles, the process including pulverizing particles of a compound represented by formula (I) with a median diameter (50% D) of over 100 μm by using a pulverizer in the presence of at least one member selected from the group consisting of silica, talc and clay, to obtain particles of the compound represented by formula (I) with a median diameter (50% D) of 100 μm or less, in formula (I), R1 and R2 each independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, or alternatively, R1 and R2 are inked to each other to form a ring together with the nitrogen atom to which they are bound, m represents an integer of 2 to 9, Mn+ represents H+ or an n-valent metal ion, and n represents an integer of 1 or 2.

    摘要： Compounds of the general formula (1) ##STR1## in which the Zs, preferably identical to each other, each denote a hydroxy group or a sulfato, thiosulfato or phosphato group. They can be prepared by first converting biphenyl by sulfochlorination into biphenyl-4,4'-disulfochloride, then reducing the latter with an alkali metal or alkaline earth metal sulfite or hydrogensulfite to sulfinic acid, and in turn reacting the latter with ethylene oxide to give 4,4'-bis-(.beta.-hydroxyethylsulfonyl)-biphenyl, which can be esterified in conventional manner. They are used for modifying and improving the physical and coloristic properties of materials made of natural and/or synthetic polyamide fibers and/or polyurethane fibers and as auxiliaries in dyeing processes for such fiber materials.
