t (U 300) (4:50). The crude BCH was then pumped to a 2 stage distillation unit for further purification; the finished BCH (M 101) being stored in a tank farm (4:50).
CPD BCH
In addition, the CPD was also mixed with chlorine to produce hexachlorocyclopentadiene (hex) at the hex unit (U 400) (4:50). This process required the following three steps:
CPD tetra
tetra octa
octa hex
Within the aldrin and dieldrin plant, the aldrin unit (U 500) manufactured aldrin from BCH (M 101) and hex (4:50).
BCH (M 101) hex HHDN and related compounds
Until early 1960, the procedure was as follows: (1) in the stirring aldrin batch reactor a measured quantity of dried M 101 from the tank park was added until the reaction was completed; (2) the heat of the reaction was removed by the evaporation of BCH, which after condensing overhead wa
