A predictive solubility tool for pesticide emulsifiable concentrate formulations was written by Kozuki, Y.;Ohtsubo, T.. And the article was included in Journal of ASTM International in 2009.Name: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:
Emulsifiable concentrates (ECs) are one of the most widely used pesticide formulations because they have a lot of advantages, such as good storage stability, relatively high biol. activity, easy weighing, easy production, and so on. An EC is normally prepared by dissolving a pesticide in a nonpolar solvent with surfactants. When a pesticide is hardly soluble in a common nonpolar solvent, a polar solvent is used as a cosolvent. One of the preferred polar solvents, which have been used for this purpose, is N-methyl-2-pyrrolidone (NMP). However, because of its toxic profile, which has recently become apparent, the com. use of NMP is recently restricted in many fields. Under the circumstances, it is desirable to look for an alternative solvent in the pesticide formulation area. The organic conceptual diagram was tried to search for the alternative solvents because it is a useful tool for predicting the physicochem. properties of an organic compound In the organic conceptual diagram, the physicochem. properties are expressed by the combination of the organic value (OV) and the inorganic value (IV). According to the theory, organic compounds that have similar IV/OV ratios (the inorganic organic balance = IOB) are mutually miscible in each other. In order to investigate the applicability of this concept to search for a suitable solvent for a pesticide that is hardly soluble in nonpolar solvents, the relation of the IOB between 2 hardly soluble pesticides (i.e., a neonicotinoid insecticide and an herbicide) and several types of solvents was evaluated. As expected, solvents having an IOB close to the targeted pesticide showed high solvency against it while the pesticide did not dissolve in solvents, which have an IOB farther off. The organic conceptual diagram can be a good tool for the selection of a solvent for a pesticide that is hardly soluble in the usual nonpolar solvents. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Name: Ethyl 3-ethoxypropanoate).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) belongs to esters. 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.Name: Ethyl 3-ethoxypropanoate
