Abstract (en)
[origin: WO2016062552A1] The invention relates to mono- and bisalkylene trialkoxysilanes of general formula (I), wherein –Y– stands for –O– or –N(R9)2-a–; each –Z– is the same or different and is selected from the group consisting of –O– and –CHR4b–; a stands for 1 if –Y– equals –O– and for 1 or 2 if –Y– equals –N(R9)2-a–; m is a natural number from 1 to 20; n is a natural number from 7 to 200; each R1 is the same or different and is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, and phenyl; and R2, R3, R4a, R4b, R5, R6, R7, R8, and R9 each stand independently for H, suitable linear or branched C1-C20 alkyl or possibly C2-C20 alkenyl, C2-C20 alkynyl, C1-C20 alkanoyl, C3-C20 alkenoyl, ω-carboxy-(C1-C6 alkyl)carbonyl, and ω-carboxy-(C2-C6 alkenyl)carbonyl and/or C7-C20 aryloyl. The invention further relates to methods for producing said mono- and bisalkylene trialkoxysilanes, the to use of said mono- and bisalkylene trialkoxysilanes as dispersants in aqueous suspensions of gravels and of hydraulic binders, and to said aqueous suspensions as such.
