prepared by co-heating n-butanol with concentrated hydrochloric acid in the presence of anhydrous zinc chloride.
used as a solvent and as a butylation reagent in organic synthesis. It can also be used in the manufacture of butyl cellulose, insect repellent, celluloid, phenylbutazone and the like.
rat oral LDso: 2670mg/kg. Inhalation of higher concentrations can cause dizziness, drowsiness and even Coma. Mild eye and skin irritation. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Protection from direct sunlight. Keep the container sealed. Should be stored separately from the oxidant.
production method | is obtained by the reaction of n-butanol and hydrogen chloride: n-butanol and concentrated hydrochloric acid are heated and refluxed in the presence of zinc chloride, the reactants are washed with water, dried, fractionated, and the 75-78.5 ℃ fraction is collected as the finished product. Raw material consumption quota: n-butanol (95%)1600 kg/t, hydrochloric acid (30%)2780 kg/t. |
production method | The preparation method is to react butanol and hydrogen chloride in the presence of catalyst ZnCl2, and wash, dry, and fractionate the product after the reaction. Reaction equation: CH3CH2CH2CH2OH + HCl[ZnCl2]& rarr;CH3CH2CH2CH2Cl + H2O |
