Paragraph 0064-0065; 0068-0075, (2021/05/11)
The present invention provides a method for manufacturing pentamethylene diisocyanate. The method for manufacturing pentamethylene diisocyanate of the present invention manufactures intermediates by using dialkyl carbonate. By thermally decomposing the intermediates under a specific polymerization inhibitor, the method can manufacture the pentamethylene diisocyanate having excellent purity in a high yield.
