| titleOfInvention | Collectors of polyquaternary ammonium polyester compounds for reverse flotation by non-sulphide ores silicate foam |
| abstract | A compound which can be obtained by condensation of at least one polyol having 3-4 hydroxyl groups or an alkoxylated product thereof, preferably glycerol or alkoxylated glycerol, having the formula ** Formula ** where Z> = - (CH2CH (CH3 ) O) m1 (CH2CH2O) or (CH2CH (CH3) O) m2T, where T is H, m1 and m2 are, independently, a number from 0-4, preferably m1 and / or m2 are 0, i is 0 or a number from 1, preferably from 2, to 10, preferably up to 5; preferably, the sum of all o's is 0; Y> = -CH2OZ, -CH2CH3 or -OZ; X> = H or CH2OZ; and V> = Z or ** Formula ** at least one dicarboxylic acid or a derivative thereof having formula (IIa) or (IIb) ** Formula ** where D is -OH, -Cl, or -OR4, where R4 is a C1-C4 alkyl group; R3 is a bond, an alkylene radical of the formula - (CH2) z-, where z is an integer from 1 to 10, preferably from 2 to 4, and most preferably 2, and where the alkylene radical can be substituted by 1 or 2 -OH groups; the group -CH> = CH-, a cycloalkylene, a cycloalkenylene or an arylene group; at least one alkanolamine having formula (III) ** Formula ** where each x is independently a number between 1 and 5, and the sum of all x, on average, is a number between 2 and 10, AO is an alkyleneoxy group having 2-4 carbon atoms, R5 is a C1-C4 alkyl group, preferably a methyl group, or [AO] xH; and at least one fatty acid having the formula R (C> = O) OH (IV) where R is a hydrocarbyl group having 7 to 23, preferably 11 to 21, optionally substituted carbon atoms; followed by reaction with an alkylating agent, suitably a C1-C4 alkyl halide, preferably methyl chloride or dimethyl sulfate wherein the procedure includes the following steps 1) reaction of a mixture consisting of at least one alkanolamine, at minus one monocarboxylic fatty acid, at least one dicarboxylic acid and at least one polyol having 3-4 hydroxyl groups, to form a polyester, and 2) quaternization of the resulting polyester by the alkylating agent. |
