3% of the 1975 chlorine market. However, Brunt believes that it has potential for replacing fluorocarbons as both a blowing agent for urethane foam and as an aerosol propellant. Its many diversified uses could support a growth rate of up to 14%
annually, but Dow pegs 9% as the most likely rate for methylene chloride. Weak chlorine markets include pulp and paper and fluorocarbons. As far as pulp and paper is concerned, Dow has made allowances for development of se quential and oxygen bleaching technology in the early 1980's. Fluorocarbon use in aerosols is in jeopardy, says Brunt, even though the ozone issue never may be re solved scientifically. Caustic soda demand last year was 9.6 million tons, down 14% from 1974. The drop, says Brunt, was caused by the combined effects of the economy, inven tory adjustments, improved methods of using caustic, and competition from al ternate alkalies. Exports were strong during the first part of 1975, but dropped dramatically in May and remained depressed the rest of the year. They accounted for 12% of U.S. caustic production last year and are ex pected to remain weak through 1985. Alumina, textiles, and rayon also are expected to be weak markets for caustic. However, caustic will benefit from the organic chemicals market, which ac counted for 34% of caustic use last year. The diversification of this group is strength in itself, says Brunt. Many new agricultural chemicals are entering the market. Nylon 6 and 66 intermediates continue to show signs of healthy longterm growth. He expects caustic demand in this group to grow 5% per year, with a low of 4% and a high of 7%. π

The urethane polymer market is back on the track. Urethanes survived the 1974-75 recessionary period and the market has recovered to match the sales rates recorded in 1973. In fact, Mobay expects polyurethane consumption this year to top the record 1.59 billion lb consumed in 1973. Speak ing at a meeting of the Chemical Mar keting Research Association in New York City, G. Thomas Harrick, director of product development in Mobay's polyurethane division, pegged this year's consumption at 1.68 billion lb. That's 8.2% better than last year. The future for polyurethanes is just as bright. He estimates that demand will increase an average 9% annually, hitting 2.37 billion lb by 1980. Flexible and rigid urethane foams will continue to be the mainstays of ure thane demand. However, first prize for rapid growth will go to the microcellular urethanes. Use of these products, used in shoe soles, structural foams, and au tomotive exterior parts, likely will in crease from its relatively low base of 28 million lb last year to 100 million to 200 million lb by 1980. That's a hefty 25 to 30% average annual growth rate. Taking 40% as a likely estimate, Harrick says that 1980 demand for microcellular ure thanes will be 150 million lb.

Total recovery of solids from 20 to 50 liters of solution or more? It's easy with Biichi/ Brinkmann Pilot Plant Rotary Evaporators.
ROTAVAPOR R-50EX (Height approx. 8 ft.)
These Rotary Evaporators make the recovery of solids from 20 to 50 liters or more of liquid an easy matter. There is no loss of material, and the result is a dry, solvent-free residue. Fast evaporation rates are possible by working under vacuum. Available in explosion-proof models with 20 and 50 liter flasks for batch and continuous feed operations.
