Silica gel of mesh 60-200 was supplied by Davison Chemical Division, W. R. Grace and Company, Baltimore, Maryland, and was dried at 70° before use. The flow rate of hexane during the chromatography was 41. per hour. 

In New York state a reprocessing plant near Buffalo began to reprocess nuclear wastes in 1966. After 6 years Nuclear Fuel Services (NFS), a subsidiary of W.R. Grace s Davison Chemical Company, abandoned the facility. There were 2 million cubic feet of radioactive material left behind along with 600,000 gallons of radioactive liquid waste that was seeping into a creek that flows into Lake Erie the source of drinking water for Buffalo. The cost of cleanup was estimated to be 1 billion.

The FCC process is the most common conversion unit in use today. As such, it is important to determine the performance of an FCC when feeding hydrotreated shale oil. The two 650° F+ feeds shown in Table VI were evaluated in an FCC pilot plant operating in a fixed fluidized-bed mode. The catalyst was withdrawn from an operating commercial FCC unit. It is a zeolite catalyst, CBZ-1, produced by Davison Chemical Division of W. R. Grace and Company and is moderately active as well as contaminated with metals. 

W. R. Grace has shrunk considerably from its earlier days as a conglomerate under Peter Grace, and it has to be considered as a specialty chemicals company from now on. Lubrizol is still a lube additives specialist with some growing activity outside its core business. But Crompton is the outcome of two mergers that have greatly expanded the portfolio of products it now manages.

The nitroparaffins produced by the vapor phase nitration of propane or ethane are available from two United States production facilities Angus Chemical Company (Sterling, LA) and W. R. Grace and Company (Deer Park, TX). This chapter discusses the naming nomenclature for the nitroparaffins, their physical properties, the various industrial uses, possible environmental concerns, and the safe handling of the nitroalkanes.
