Specification
Purity：≥99%
Melting point: 40-42°C(lit.)
Solubility: miscible soluble in ether, chloroform, glycerin, carbon disulfide, petroleum jelly, volatile oil, strong alkali aqueous solution. Easy to dissolve in ethanol, glycerin, chloroform, ether and other organic solvents at room temperature, slightly soluble in water at room temperature, mixed with about 8% water can be liquefied, more than 65℃ can be miscible with water, almost insoluble in petroleum ether.
Chemical properties: Can absorb moisture in the air and liquefied. A very thin solution has a sweet smell. Highly corrosive. Strong chemical reaction ability. Reaction with aldehydes and ketones to produce phenolic resin, bisphenol A, reaction with acetic anhydride, salicylic acid to produce phenyl acetate, salicylic acid ester. It can also carry out halogenation, hydrogenation, oxidation, alkylation, carboxylation, esterification, etherification and other reactions. Phenol is solid at normal temperature and cannot react with sodium smoothly. If the method of melting phenol by heating and adding sodium metal is used for the experiment, phenol is easy to be reduced, and the color of phenol changes during heating, which will affect the experimental effect. Some people in the teaching to take the following method experiment, simple operation, achieved satisfactory experimental results. Add 2-3 milliliters of anhydrous ether into a test tube, take a piece of metal sodium about the size of a soybean grain, blot the kerosene on the surface with filter paper, and put it into the ether. It can be seen that the sodium does not react with the ether. Then add a small amount of phenol to the test tube, shake it, and observe the rapid reaction of sodium in the test tube，A lot of gas is produced. The principle of this experiment is that phenol is dissolved in ether, allowing the reaction of phenol with sodium to proceed smoothly.
Use:
Phenol is an important organic chemical raw material, which can be used to produce phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, 2, 4-D, adipic acid, phenolphthalein n-acetylethoxyaniline and other chemical products and intermediates. In chemical raw materials, alkyl phenols, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings and oil refining industry has an important use. In addition, phenol can also be used as a solvent, experimental reagent and disinfectant. The aqueous solution of phenol can separate the proteins from DNA on the chromosomes in plant cells, which is convenient for DNA staining. Widely used in the manufacture of phenolic resin, epoxy resin, nylon fiber, plasticizer, developer, preservative, insecticide, fungicide, dye, medicine, spices and explosives.
Storage method:
1. Store in cool and ventilated warehouse. Keep away from fire and heat. Avoid light. The temperature of the storage room should not exceed 30℃, and the relative humidity should not exceed 70%. The package is sealed.
2. It should be stored separately from oxidants, acids, alkalis and edible chemicals, and should not be mixed. Equipped with the corresponding variety and quantity of fire equipment.
3.the storage area should be equipped with appropriate materials to absorb the leakage. The "five pairs" management system for extremely toxic substances should be strictly implemented.
