| titleOfInvention | Method for continuously preparing 1,5-naphthalene diisocyanate |
| abstract | The invention discloses a method for continuously preparing 1,5-naphthalene diisocyanate, and the method comprises the following steps of: firstly mixing a 1,5-naphthalene diisocyanate solution and a di(trichloromethyl) carbonate solution into a reaction raw material, and then carrying out continuous charging; enabling the reaction raw material to firstly flow through a tubular reactor at the temperature of 25-100 DEG C and then flow through 3-8 stage series-connected combined slot type reactors, and enabling an obtained mixture to flow out of the last-stage reactor; and filtering, and then concentrating and crystallizing filter liquor to obtain the 1,5-naphthalene diisocyanate. The method disclosed by the invention has the advantages of high reaction yield, high product purity, short reaction time, high equipment utilization ratio, low production cost, no pollution, continuous production and industrialized application. |
