使用
2-Ethylhexanoic acid is used in the preparation of metal derivatives, which act as a catalyst in polymerization reactions. For example, tin 2-ethylhexanoate is used in the manufacturing of poly(lactic-co-glycolic acid). It is also used as a stabilizer for polyvinyl chlorides. It is also involved in solvent extraction and dye granulation. Further, it is used to prepare plasticizers, lubricants, detergents, flotation aids, corrosion inhibitors and alkyd resins. In addition to this, it serves as a catalyst for polyurethane foaming.
製造方法
In a dry 1L three-neck bottle, Add isooctyl aldehyde (80g, 0.62mol) And the solvent 2-ethylhexanoic acid (240g, 1.66mol), ligand L8 (5.24mg, 0.007mmol), cesium carbonate (18.24mg, 0.056mmol), potassium acetate 160mg, placed in a water bath, mechanical under nitrogen atmosphere Stir, after the temperature rises to 30 ° C, Air flow was started at a flow rate of 11.9 g/h, and the reaction temperature was maintained at 30-35 ° C by adding cooling water to the water bath. After 6 hours of reaction, the conversion of isooctyl aldehyde was calculated to be 99.6%. The selectivity of 2-ethylhexanoic acid was 99.5%, and the yield was 99.10%.
一般的な説明
2-Ethylhexanoic acid is a colorless to light yellow liquid with a mild odor. 2-Ethylhexanoic acid will burn though 2-Ethylhexanoic acid may take some effort to ignite. 2-Ethylhexanoic acid is slightly soluble in water. 2-Ethylhexanoic acid is corrosive to metals and tissue. 2-Ethylhexanoic acid is used to make paint dryers and plasticizers.
健康ハザード
Harmful if swallowed, inhaled or absorbed through skin. Material is extremely destructive to tissues of mucous membranes and upper respiratory tract, eyes and skin. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx, bronchii, chemical pneumonitis and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
火災危険
2-Ethylhexanoic acid is combustible.
安全性プロファイル
Moderately toxic by
ingestion and skin contact. An
experimental teratogen. A skin and severe
eye irritant. Combustible when exposed to
heat or flame. When heated to
decomposition, it emits acrid and irritating
fumes.
