FIELD: chemistry.

SUBSTANCE: invention relates to new derivatives of tris(2-hydroxyphenyl)-methane having the general formula (I), with surface-active properties, where

R are independently of one another, 0 to 4 unbranched or branched aliphatic hydrocarbon radicals having 1 to 6 carbon atoms per phenyl ring,

R¹ is a radical selected from the group consisting of hydrogen, hydroxyl and hydrocarbon groups having 1 to 6 carbon atoms,

R² are independently of one another, radicals of the general formula (III) -(R⁵-O-)_n-R⁶-X, where n is a number from 1 to 50,

and where the radicals R⁵ independently of one another, are selected from the group consisting of radicals R⁷, R⁸ and R⁹: ,

where R⁶, X, R¹⁰ and R¹¹ independently of one another, have the following meaning:

R⁶ is a single bond or an alkylene group having 1 to 10 carbon atoms,

X is hydrogen or a hydrophilic group, where the hydrophilic group is an acidic group or a radical which comprises at least one OH group,

R¹⁰ is hydrogen or an aliphatic hydrocarbon radical having 1 to 6 carbon atoms,

R¹¹ is a group -(R⁵-O-)_m-R⁶-X, where m is a number from 0 to 50,

and where the total number z of all groups R⁵ in a radical R² is 1 to 50 with the proviso that z is a number from 2 to 50, if at least one X is hydrogen.

EFFECT: preparation of derivatives of tris(2-hydroxyphenyl)methane.
