Dear Doctor Greenlee: I appreciated the. opportunity to discuss;`theoperating characteristics of your fractional- distillation columns'with you very muoh. When large volumes or material.are-to-be distilled, the metal helix and extruded packings certainly .have an advantage from the standpoint of throughput. Should - you happen to find a need, for a packing with lower hold-up per foot, and smaller H*:E;T.P.>, you .might .be Interested in the wire-screen type described by John and Rehberg in Ind. Eng. Cham,, kl, 1056 (19k9) have built three suoh columns, vising 80xo0 mesh stainless steel screen (.0055" wire), and have been able to confirm the authors' olalm for efficiency. .: we are interested in the possibility of obtaining samples of 1-phonyldecane and 1-oyolohexyldecane in connection with basic physiological studies for API Research Projeot MC-1. VW should appreciate further information regarding the avail ability of these hydroearbona In 100 gram lots of 98* % purity. With best regards, .Sincerely yours. AWHmJg eno: . A.
