Abstract (en)
[origin: EP0368041A1] Coal briquets bound by starch or starch derivatives, having a reduced water absorption capacity and containing, based on starch, 0.2 to 10% by weight of organosilicon compounds obtainable by mixing a methylpolysiloxanol, in which up to 10% of the methyl groups may be replaced by phenyl groups, with a silane of the formula R<3>-Si(OR<2>)3 where R<2> is a lower alkyl radical having 1 to 4 carbon atoms, R<3> is an aminoalkyl radical having 1 to 6 carbon atoms or the H2N-(CH2)xR<4>(CH2)y- radical where R<4> is oxygen, sulphur, -NH- or -NH-CH2-CH2-NH-, x >/= 3 and y >/= 2, or an epoxyalkyl radical of the formula <IMAGE> where n is an integer from 1 to 6, with one another in such amounts that one SiOH group from the polysiloxanol corresponds to > 1 to 3 OR<2> groups, and the mixture is warmed, if desired, to temperatures of at least 50 DEG C. The invention furthermore relates to a process for the production of the briquets by suitable admixing of the abovementioned organosilicon compounds.
