In this work, a facile method for determination of foaming properties of frothers was used. It was based on measuring the foam height in a flotation machine at different concentrations of frothers. Based on the foam height-concentration curve, a new foaming parameter, so-called concentration at half of the maximum foam height CMH, was proposed. Assessment and usefulness of CMH were shown in flotation of quartz. The concentration of amine at the critical contact angle CCA, at which amine starts to be a collector, was also determined The determined values of CCA were similar to CMH and were equal to 1.3, 0.14 and 0.03 mM for ButNH2, HexNH2 and OctNH2, resp. The values of CMH and CCA depended on the alkyl chain of frothers. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 112-59-4
