Process manufacturing tecnology.

INTRODUCTION The aim of this assignment is to examine the production of a pharmaceutic intermediate. A mode of processing is to be selected and justified, and a plate of the operation identified including the major items of processing found and method operation. The implication of the selection with respect to safety, health and environment should be taboolined for current and future operations. The reception was initially carried break in chloroform. Due to the undesirable health properties of chloroform it was substituted by dichloromethane. Reaction times with this solvent were extended and it was subsequently replaced by an excess of still A. The dissolution of unfaltering A in Liquid A and the subsequent reaction both rest to be endothermic. Gaseous waste products from the reaction can be a problem if not controlled or abated. Liquid A loss may also be significant. Neither of the reactions ply alone proceed satisfactorily at room temperature. The reaction of the un assailable A and Liquid A is much speedy than the abeyance down of the intermediate to Liquid B. In site to further the reaction identify of the second reaction the temperature essential be raised and to achieve this the excess Liquid A is take away by distillate. Typical reaction/temperature curves atomic number 18 appended. The typical reaction efficiency is 97% with respect to square(a) A. Final recovery of the Liquid B is by distillation at 55 deg.

C under vacuum. There ar some solid wastes from the reaction including the balance wheel Solid A. These wastes are soluble in Liquid B. The needed purity o f Liquid B is >99%. Initial production c! ome out is: 100 T/a The forecast demand is: one hundred ten T/a in year 2 cxxv T/a in year 3 one hundred sixty T/a in year 4 206 T/a in year 5 There is no forecast beyond year 5 but it is anticipated...
