Previously, the sole owner of Pitts- burgh Chemical's 51,000 shares was Pittsburgh Coke & Chemical. Pittsburgh Chemical also borrowed $10.4 million in bank loans guaranteed by U.S. Steel and Pittsburgh Coke to pay off certain debts it owed the parent company. A spokesman for U.S. Steel says the firm acquired its interest in Pittsburgh Chemical to retain an outlet for coal tar naphthalene which U.S. Steel produces at its Clairton, Pa., works. Pittsburgh Chemical's phthalic anhydride plant on Neville Island can use either o-xylene or naphthalene feedstock. Phillips Petroleum has acquired 540,000 shares of authorized but previously unissued shares of Purex Corp.'s common stock for cash. After the issue, the shares represent about 8% of Purex's common stock. Purex president Alan Stoneman says the sale will enable Purex to sim- plify its capital structure and improve its working capital. Purex, Lakewood, Calif., makes bleaches, detergents, soaps, cleansers, and other household cleaning products. Its sales were $117 million for the year ended June 30, 1962. Mr. Stoneman says that Purex has no intention of merging with Phillips or selling it any additional stock. ί Float glass will soon be made within the European Common Market. France's Claces de Bouiois and Saint Gobain have both acquired manufacturing rights from Britain's Pilkington Brothers, developers of the process. Saint Go- bain plans to start building the first float glass plant in Italy. The float glass process eliminates the expensive grinding and polishing operations in plate glass manufacture (C&EN, March 23, 1959, page 41 ). Last year, Pittsburgh Plate Glass was the first to license the process from Pilkington ( C&EN, Aug. 6,1962, page 41 ). • Southern Nitrogen Co. is discussing merger plans with a company it declines to name. Formed about eight years ago by four former executives of Spencer Chemical, Southern Nitro- gen started producing fertilizer in 1957. Last year, sales hit $19.9 million; earnings reached $1.7 million. The company has a 460 ton-a-day am- monia plant and units for making ammonium nitrate, urea, and other nitrogen fertilizer prod- ucts at Savannah, Ga. Its main marketing area is in the Southeast, although it does sell nitrogen fertilizers as well as mixed goods in the midwest- ern states. • Union Carbide Chemicals is building a new plant to make sorbic acid and potassium sor- bate at South Charleston, W.Va. The new unit, which should be on stream by the fourth quarter of this year, will replace Carbide's existing sorbic acid plant there and will, at the same time, triple the company's capacity. Although Carbide won't reveal exact capacity, it says the plant will be big enough to supply current world demand for sorbic acid. Principal use of sorbic acid and its potassium salt is in food products as a fungistat and as an antimycotic. ^ Dow Corning has cut its high-purity silicon prices 10 to 40%. The reductions range from 10 to 25% on one-piece crucible charges of poly- crystalline silicon and to about 40% on float-zone refined single crystal silicon. High-purity silicon producers, Monsanto Chemical, Merck & Co., Trancoa Chemical, Allegheny Electronic Chemi- cals, and Union Carbide's Linde Co. division, all say they will remain competitive. Texas Instru- ments, the largest producer of high-purity silicon, says that the move merely adjusts prices to meet the market. On the other hand, Dow Corning is raising the price of trichlorosilane, one of the basic materials used to produce silicon, from 73 cents to 90 cents a pound, tank truck quantities. Union Carbide, a major producer of silane, says it has no plans to raise the price of its material. ί Schering Corp. has set up a new marketing subsidiary in Milan, Italy. Essex (Italia, S.p.A. ). The move is part of Schering's plan to replace its distributors in European Common Market coun- tries by operations which would be directly con- trolled by Schering's management, president Francis Brown told the company's annual stock- holders meeting. Schering is also negotiating to acquire a French drug company and is consider- ing the formation of a new West German com- pany which would be jointly owned with a Ger- man pharmaceutical firm.
