DL-乳酸 (CAS No.598-82-3)
- 物化性质
- 乳酸纯品为无色液体，工业品为无色至浅黄色液体，无气味，具有吸湿性。相对密度1.2060（25/4℃），熔点18℃，沸点122℃（2kPa），折射率1.4392（20℃）。能与水、乙醇、甘油混溶，不溶于氯仿、二硫化碳和石油醚。在常压下加热分解，浓缩至50%时部分变成乳酸酐，因此产品中常含有10%-15%的乳酸酐。
- 技术参数

English description（英文原文，共 1239 字符）
Product Name:DL-Lactic acid
English Name:DL-Lactic acid
CAS No.:50-21-5
Aliases:2-Hydroxypropionic acid, α-Hydroxypropionic acid, Propanoic acid, 2-hydroxy-
Molecular Formula:C3H6O3
Physical Properties:Pure lactic acid is a colorless liquid, while the industrial product is a colorless to light yellow liquid with no odor and hygroscopicity. Relative density is 1.2060 (25/4°C), melting point is 18°C, boiling point is 122°C (2 kPa), and refractive index is 1.4392 (20°C). It is miscible with water, ethanol, and glycerol, but insoluble in chloroform, carbon disulfide, and petroleum ether. It decomposes upon heating under normal pressure; when concentrated to 50%, it partially converts into lactic anhydride, so the product usually contains 10%-15% lactic anhydride.
Uses:Mainly used as an acidity regulator in food and beverages, providing a sour taste and inhibiting microbial growth. In the pharmaceutical industry, it is used to prepare drug intermediates. It is also used in cosmetics and daily chemical products as a pH adjuster and moisturizing ingredient.
