5. Use of Benzyl chloride
Benzyl chloride is usually being the material of making the dye, spice, medicine, synthetic tannin and synthetic resin. Besides, Benzyl chloride could also used as an very important organic synthesis intermediate. When in pesticide, it could directly synthesis the organophosphorus fungicide and could be used as the vital material in many other intermediates, such as in synthesis of benzyl cyanide, benzoyl chloride and MPA. As for its product categories, they are various, including pharmaceutical intermediates; organics; biochemistry; reagents for oligosaccharide synthesis.
6. Preparation of Benzyl chloride
The Benzyl chloride could be produced with great amount with the following chemical reaction: C6H5CH3 + Cl2 →C6H5CH2Cl + HCl.
7. Other details of Benzyl chloride
Benzyl chloride is a kind of Colorless to yellow liquid with very strong pungent odour and it has tearing property. Besides, it is soluble in diethyl [ethyl] ether, alcohol, chloroform and other organic solvent but insoluble in water. It is unstable and combustible, so inhibitors such as propylene oxide or trimethylamine are usually added to prevent polymerization. Above flash point vapour-air mixtures are explosive within the limits noted above. Contact with water produces toxic fumes. What's more, it is incompatible with strong oxidizing agents, water, acids, most common metals, dimethyl sulfoxide. So while storing it, it should be kept with the storage temp. of 0-6°C, and in a dry, cool, and well-ventilated storeroom, away from other oxygenant and food additives.
Being among the toxic chemicals, it at low levels cause damage to health and it is toxic if by inhalation and in contact with skinmay, then it could even cause cancer. Besides, it is irritating to respiratory system and skin and it has risk of serious damage to eyes. What's more, it has the danger of serious damage to health by prolonged exposure if swallowed. So while dealing with this chemical, we should take the following instructions. Avoid exposure - obtain special instructions before use, and if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). You could also refer to WGK Germany 3 to obtain more safety information.
