Abstract: A polyisocyanate production method that can allow effective use of hydrogen chloride produced secondarily in a polyisocyanate production process, while allowing reduction of environmental burdens, and a polyisocyanate production system for performing the polyisocyanate production method. After chlorine is allowed to react with carbon monoxide to produce carbonyl chloride in a carbonyl chloride producing reactor, the carbonyl chloride produced in the carbonyl chloride producing reactor is allowed to react with polyamine in an isocyanate producing reactor to produce polyisocyanate. Then, after hydrochloric gas produced secondarily in the isocyanate producing reactor is purified in a hydrogen chloride purifying column, the purified hydrochloric gas is oxidized in a hydrogen chloride oxidizing reactor to produce chlorine.

Abstract: An apparatus for continuously producing polyisocyanate is provided for quickly contacting polyamine and carbonyl chloride in order to suppress an undesirable reaction between polyamine and polyisocyanate so that a by-product can be reduced and the yield of polyisocyanate can be improved. In a circulatory line 7, a material-mixing portion 8, a high-shear pump 3, a reactor 4, a liquid-feeding pump 5 and a cooler 6 are interposed in series along the direction of the flow of a reaction solution, thereby forming a closed line. In this apparatus 1, after polyamine and carbonyl chloride are supplied in the material-mixing portion 8, the reaction solution is sheared by the high-shear pump 3 in a state where the contact of the polyamine with the reaction solution is minimized. Thus, the formation of a urea compound as a by-product can be suppressed and the yield of polyisocyanate can be improved.
