Uses
The PROPYL CHLOROCARBONATE(109-61-5) is used as a flotation agent and reagent in organic synthesis.N-propyl chloroformate is a bactericide Propamocarb intermediates.
Production
Its preparation method is to add light through gas tank n-propanol, start stirring, and then pass into the flow meter phosgene phosgene, Tung-ray air temperature is 30 ℃ or so and continue to pass phosgene for a number of hours, close to the finish line sampling and analysis , compliance to cease pass phosgene, cooling, and then pass rush emptied of nitrogen gas and hydrogen chloride, phosgene and sabotage, sampling and analysis for the product. Reaction equation: CH3CH2CH2OH + COCl2 → ClCOOCH2CH2CH3
