Continuous process for the nitration of cellulose and apparatus therefor |
摘要 |
In a continuous process for the nitration of cellulose, a slurry of cellulose in nitrating liquor is injected under pressure into a primary nitration reactor by means of an injection pump, the reactor comprising a loop of tubing, the slurry is circulated in the loop by means of a circulation pump at a rate which is greater than the rate of injection in order to ensure that the slurry is vigorously agitated, the slurry is optionally transferred, successively, from the primary loop to one or more secondary nitration reactors, each of which also comprises a loop of tubing equipped with a circulation pump, and the slurry is withdrawn from the final loop and the nitrocellulose is recovered.
