摘要:
Gel compositions comprising a thickener and a surfactant component including an alkoxylated carboxylic acid ester corresponding to general formula (I): wherein R1C(O) represents an aliphatic acyl group, each AlkO independently represents an alkoxylate selected from the group consisting of CH2CH2O, CHCH3CH2O and CH2CHCH3O, n is a number of from 1 to 20, and R2 represents an aliphatic alkyl group, are described. The use of such gel compositions in methods of providing controlled release of cleaning agents to toilets is also described, in addition to the containers used in such methods.
摘要:
Finely divided solids suspensions can be dewatered by adding to the solids suspension a mixed hydroxy ether of the formula ##STR1## wherein R.sup.1 is a linear hydroxy alkyl group containing from 2 to 16 carbon atoms with the hydroxyl group on the carbon atom adjacent to the carbon atom with the ether linkage and R.sup.2 is a linear alkyl group with 1 to 15 carbon atoms with the proviso that the sum of the total carbon atoms in R.sup.1 and R.sup.2 is 5 to 17, R.sup.3 is a linear or branched alkyl group with 1 to 12 carbon atoms and n is a number of from 1 to 20. The mixed hydroxy ethers are readily biodegradable, generate very little foam and have a low solidification point.
摘要:
Fine-particle solids suspensions can be dewatered by a process in which dialkyl carbonates corresponding to formula (I) ##STR1## in which R.sup.1 and R.sup.2 independently of one another represent alkyl and/or alkenyl groups containing 1 to 22 carbon atoms andm and n independently of one another stand for 0 or numbers of 1 to 10,are used as auxiliaries. The auxiliaries are readily biodegradable, extremely low-foaming and are distinguished by a low solidification point.
摘要:
The use of mixed hydroxyethers of the general formula IR.sup.1 O--(CH.sub.2 CH.sub.2 O).sub.x --CH.sub.2 --CH(OH)R.sup.2 (I)in whichR.sup.1 denotes an alkyl group having 1 to 10 carbon atomsR.sup.2 denotes an alkyl group having 8 to 20 carbon atoms and x denotes a number in the range from 1 to 20 as auxiliaries for the dehydration of water-containing finely divided solids, gives solids having a low water content without foaming in the water separated therefrom.
摘要:
A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.
摘要:
Mixtures of(a) at least one alkyl or alkenyl polyethylene glycol ether which is terminally blocked by a hydrophobic radical, and(b) at least one anion-active surfactant are used as collectors in the flotation of non-sulfide ores.
摘要:
A process for separating non-sulfidic minerals from an ore by flotation in which the ore is contacted with a mixture of(a) at least one adduct of ethylene oxide and propylene oxide with a C.sub.8 -C.sub.22 fatty alcohol and(b) at least one anionic, cationic or ampholytic surfactant.
摘要:
Fatty alcohol polyglycol ethers terminally blocked by hydrophobic radicals are used as co-collectors together with cationic or ampholytic surfactant components in the flotation of non-sulfidic ores.
