Box 14538 St. Louis,M0 63178-4538 Dear Bob: I spoke to our technical laboratory regarding the equilibrium vapor concentration for ALFOL 6 Alcohol. It was not clear to them how you would want this figure calculated. However, based on a vapor pressure of 1,0mm of mercury at 25C, and using the ideal gas laws, the calcu lated value would be approximately 0.5 weight per cent in air or approx imately 1320 ppm. Sincerely, Thomas G. Grumbles, C.I.H. Director, Industrial Hygiene TGG/akh CCR 00000037a
