Analyze column forward flow samples to detarmina when column la putgad of MCS 1109 material.
JU*TIIC ATIOH-.
The department wanta to determine If prevloua data on column purging after product change-over la valid and to minimize purge t ime.
tutsisavi
A recent monoehlorobiphany1 production run gave the department the opportunity to determine how much purging is required to minimize cross contamination during column change-over from monochloroblphcnv1 * to MC5 1016. Four samples were submitted. The as.-tple composition wee determined by CC procedure used to control distillation and product oualltv of tha above rapnochlorollpheuyIs demonstra11 or. The first two cute were crystalline ann tne first cut rc trace droplets of brown oil dispersed throughout the sample vrich rote to the top aa the sample was nelted. t.'t were unable to sample the brown layer. The analytical results irt attached.
