| | L-(-)-乳酸 エチル Usage And Synthesis |
| 外観 | 無色～ほとんど無色透明液体 | | 化学的特性 | clear liquid | | 使用 | Ethyl L-lactate is used in the preparation of food additives, aryl aldimines, fragrances and in pharmaceutical preparations. It can be considered as a green solvent in chemical industries due to its biodegradable nature. As a solvent, it used in the production of nitrocellulose, cellulose acetate and cellulose ethers. | | 使用 | (-)-Ethyl L-Lactate is a naturally occuring chemical compound that is often used as an industrial solvent in chemical reactions. | | 定義 | ChEBI: The (2S)-enantiomer of ethyl lactate. | | 一般的な説明 | Ethyl?lactate is an economically viable?green solvent used in organic synthesis. It is generally employed in organic reactions like multi-component reactions, cycloaddition reaction, asymmetric induction, photochemical synthesis, and ligand-free coupling reactions, etc. | | 燃焼性と爆発性 | Non flammable |
