colorless or pale yellow oily liquid. With ethanol, acetic acid miscible, soluble in ether, slightly soluble in water.
salicylic acid was added to the reaction vessel, excess methanol was added thereto, and the reaction was carried out by adding the catalyst sulfuric acid with stirring and heating. After completion of the reaction, the reaction mixture was washed with water until neutral. After distillation, methanol and residual water were distilled off under normal pressure, and the fractions were collected by distillation under reduced pressure.
The printing and dyeing industry is used as a high temperature heat carrier.
rat oral, dog oral, guinea pig oral LD50:887mg/kg, 2100mg/kg, 700mg/kg. On the skin irritation. Vapor or smoke has a irritating effect on the eyes, mucous membranes, and upper respiratory tract. In case of high heat, open flame or contact with oxidant, there is a risk of combustion. In case of high fever, the internal pressure of the container increases, and there is a risk of cracking and explosion. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from the oxidant, acid, alkali.
