Abstract: Deflocculating agents for increasing the strength of clay bodies have a formula R1-CONH-(R2NH)n-R3NHCOR4 or R5R6N-R2-(NHR2)m-NHCOR4 wherein R1 and R4 are C3 or C4-g -hydroxyalkyl groups, R2 and R3 are C2-4 alkylene groups, R5 is a C1-20 alkyl, alkenyl, hydroxyalkyl, alicyclic (including abietyl), aryl, aralkyl or heterocyclic group (e.g. pyrrolidyl, piperidyl, morpholinyl, or imidazolidyl), R6 is hydrogen or a C1-20 alkyl or hydroxyalkyl group, or R5 or R6 taken together with the nitrogen to which they are attached represent a heterocyclic ring (e.g. morpholine), m is an integer of from 0 to 4 and n is an integer of from 1 to 4.  Substances of the above formulae may also be used as thickening agents for oils. Thus, in examples, a substance obtained by reacting gammabutyrolactone with diamine RNHCH2CH2CH2NH2, where R is derived from coconut fatty acid, is used to thicken light mineral oil or to gel kerosene.ALSO:The invention comprises compounds of formul\m 9 R1-CONH-(R2NH)n-R3NHCOR4 (1) and R5R6N-R2-(NHR2)m-NHCOR4 (2) wherein R1 and R4 are C3 or C4-g -hydroxyalkyl groups, R2 and R3 are C2-4 alkylene groups, R5 is a C1-20 alkyl, alkenyl, hydroxyalkyl, alicyclic (including abietyl), aryl, aralkyl or heterocyclic group (e.g. pyrrolidyl, piperidyl, morpholinyl, or imidazolidyl), R6 is hydrogen or a C1-20 alkyl or hydroxyalkyl group, or R5 and R6 taken together with the nitrogen to which they are attached represent a heterocyclic ring (e.g. morpholine), m is an integer of from 0 to 4 and n is an integer of from 1 to 4.  The compounds are prepared by heating one mole. of an alkylene polyamine of the formula H2N-(R2NH)n-R3NH2 or R5R6N-R2 (NHR2)m-NH2 with one mole. (for compounds of formula 2) or two moles. (for compounds of formula 1) of either g -butyrolactone or m -valerolactone.  The products are added to fire extinguishers, resins, spinning baths, pesticides, oil wells; and to alkyd resin paints to promote thixotropy; they may be used in the treatment of rubber latex, leather, textiles, hair and paper; they may be used for ore flotation and as collectors in froth flotation processes, as corrosion inhibitors in oil-well brine, mineral lubricating oils and cutting oils (particularly to prevent rusting of iron and steel), as deflocculating agents for increasing strength of clay bodies and for gelling kerosene to give incendiary compositions.ALSO:Compounds of formulae R1-CONH-(R2NH)n-R3NHCOR4 (1) and R5R6N-R2-(NHR2)m-NHCOR4 (2) wherein R1 and R4 are C3 or C4-g -hydroxyalkyl groups, R2 and R3 are C2-4-alkylene groups, R5 is a C1-20-alkyl, alkenyl, hydroxyalkyl, alicyclic (including abietyl), aryl, aralkyl or heterocyclic group (e.g. pyrrolidyl, piperidyl, morpholinyl, or imidazolidyl), R6 is hydrogen or a C1-20-alkyl or hydroxyalkyl group, or R5 or R6 taken together with the nitrogen to which they are attached represent a heterocyclic ring (e.g. morpholine), m is an integer of from 0 to 4 and n is an integer of from 1 to 4, are added to alkyd resin paints to promote thixotropy.ALSO:Compounds of formulae R1 - CONH - (R2NH)n - R3NHCOR4 (1) and R5 R6N - R2 - (NHR2)m - NH COR4 (2), wherein R1 and R4 are C3 or C4 - g  - hydroxyalkyl groups, R2 and R3 are C2-4 alkylene groups, R5 is a C1-20 alkyl, alkenyl, hydroxyalkyl, alicyclic (including abietyl), aryl, aralkyl or heterocyclic group (e.g. pyrrolidyl, piperidyl, morphonlinyl, or imidazolidyl), R6 is hydrogen or a C1-20 alkyl or hydroxyalkyl group, or R5 and R6 taken together with the nitrogen to which they are attached represent a heterocyclic ring (e.g. morpholine), m is an integer of from 0 to 4 and n is an integer of from 1 to 4 used as collectors in froth flotation processes.
