could b e used in the chemical industry on a larger scale, but separation of oleic acid from red oil has been difBcult and costly, the USD A report states. The Eastern Laboratory's research team solved the problem by treating die original animal fat with hydrogen. T h e hydrogen reacted with most of the undesirable chemical compounds in t h e fat ( polyunsaturated acid glycerides ) and converted them to more useful compounds ( monounsaturated acid glycerides *. The treated fat, when processed to yield oleic acid, gave an acid of 90 to 9S r < purity. The process, designed to use available industrial equipment, was checked in the Eastern Laboratory's pilot plant, a n d the engineering and cost studies showed that t h e puiified oleic acid would cost only

Mew Specialized Grade of Sodium CMC Shows Great Promise in Textile, Ceramic and Papermaking Applications Carbose I Proves Itself Efficient Glaze Binder Carbose Γ has already found wide use as a glaze binder. In structural tile, it lessens or eTimfnates framing and also increases the dry film strength. In pot teries^ it helps produce an excellent uniformity in the glaze mixture. As a rniE addLitionv it gives improved strength to» porcelain enamels. A synthetic made under close control, Carbose Γ is consistently uniform. It offers six advantages: (1) With it. the viscosity of glazes can b e controlled from batch to- batch much easier than with vegetable gums. (2) Solutions of Car bose I can stand a long time without de terioration. (3) It needs no ρ re-dissolv ing:. (4) It prevents settling of glazes. (;5)' It toughens unfired glazes, improves binding- (6) It produces a smooth finish.
Carbose I Effective in Surface and Beater Applications Closely related to cellulose in chem ical nature. Carbose I has many uses in papermaking. It can be conveniently applied from water solution to the paperboard- as the board passes through the calendar stack. The solution, drying rapidly, forms a well-bonded surface film on tL
