Abstract: A process for fluidizing an aqueous suspension of mineral particles or hydraulic binder pastes which comprises admixing said aqueous suspension of mineral particles or hydraulic binder pastes with one or more compounds or salts of compounds corresponding to the general formula: ##STR1## wherein: R is a hydrogen atom or a saturated or unsaturated monovalent hydrocarbon group comprising 1 to 18 carbon atoms and optionally one or more heteroatoms;R.sub.i is an alkylene or an arylene group optionally comprising one or more heteroatoms;Q is a hydrocarbon group comprising 2 to 18 carbon atoms and optionally one or more heteroatoms;A is an alkylidene group comprising 1 to 5 carbon atoms;R.sub.j is selected from the group consisting of an A-PO.sub.3 H.sub.2 group, an alkyl group comprising 1 to 18 carbon atoms and the group ##STR2## wherein R.sub.k is selected from the group consisting of an A-PO.sub.3 H.sub.2 group and an alkyl group and B is an alkylene group;n is 1 to 10,000;r is the sum of ?R-O(R.sub.i -O).sub.

Abstract: A process for the preparation of polyoxyalkylated compounds comprising at least one primary or secondary amine function is provided comprising reacting at least one amino-alcoholate (B) produced from an amino-alcohol (A) including at least one OH group and at least one primary or secondary amine function, by replacing a fraction or all the OH groups by OM groups, M being selected from sodium, potassium, rubidium and cesium, with an oxirane, a mixture of oxiranes or a sequence of oxiranes, in an aprotic and anhydrous solvent, in an anhydrous atmosphere and at a temperature of between about 0.degree. C. and 200.degree. C.
