Twelve to thirteen thousand tons of titanium were available in 1956 and present construc tion schedules indicate that the figure will rise substantially in 1957. U.S.I.'s new plant alone will add 5,000 tons to the annual pro duction capacity by the end of the year. Zirconium will be on the market in quantity by mid-1957. When its new plant at Ashtabula, Ohio gets under way, U.S.I, will be able to supply 500,000 pounds or more per year to commercial users in addition to its Atomic Energy Commission commitments of 1.000,000 pounds per year. New M e t a l s E c o n o m i c a l Chemical process equipment can now be fabricated from titanium for a little over twice the price of stainless steel, and it is expected that in the future titanium equipment will be only 50-75% higher than stainless. ' Com mercial grade zirconium equipment will prob ably be priced only 75-100% higher than stainless when volume production is reached. Several other factors combine to make zir conium and titanium economical as corrosionresistant materials of construction. For many of the more difficult-to-handle chemicals, espe cially chlorides and oxidizing acids, equip ment fabricated from these metals can have extremely long service life. Product contami nation can be virtually eliminated in chemi cal and food handling processes. C o r r o s i o n r e s i s t a n c e s of z i r c o n i u m a n d titanium to typical chemicals are presented in the chart on page 1.
Methionine Increases P r o t e i n Utilization Of Dried Fish Meal Supplementation of commercial fish meal with DL-methionine, an essential sulfur-con taining amino acid, raises significantly the net protein utilization of the meal, according to a report recently published in England. During the drying process, the action of heat in the presence of moisture is said to impair the protein quality of fish meal. Methi onine becomes the chief limiting amino acid, and increasing the methionine content of the fish meal through supplementation restores most of the protein value of the meal.
Reactor
TECHNICAL
U.S.I. plans to look into new and more effi cient processes for the production of a wide variety of chemicals through research at the proposed installation. Participation in the project will also enable U.S.I, to make further studies on materials for nuclear reactors. The company is a major producer of metallic sodium, used as a heat transfer medium for certain types of reactors. And zirconium will be produced by U.S.I, in the near future under a contract with the Atomic Energy Commission. Zirconium is a key structural material for atomic reactors and a raw material for the production of reactor fuel elements. The company is vitally interested in developing still other materials and chemicals used in the generation of atomic power.

"U.S.T. I s o s e b a c i c " acid and related prod ucts. Mr. Faye joined the U . S . I . - N a t i o n a l Dis tillers organization in 1952 in the Market Re search and Development Department, where he was responsible for commercial develop ment of "U.S.I. Isosebacic" acid. "U.S.I. Isosebacic" is the registered trade mark for a mixture of 10-carbon dibasic acids produced synthetically for the first time by a U.S.I.developed process. A 10.000,000 pound-peryear plant to produce this material is under construction at U.S.I.'s Tuscola, Illinois plant site, and is expected to be in operation by mid-1957.

Information about manufacturers of these items may be obtained by writing the Editor, U.S.I. Chemical News. Polyethylene "pillows" to retard evaporation of liquids in open tanks and vessels are now being produced. They are air-filled, % " by 1 W by V2" in size. Α Ιΐ/2" layer is claimed adequate for solutions at any concentration. No. 1190 Monomethylol dimethyl hydantoin, now produced commercially, is offered as an almost odorless donor of formaldehyde and for reaction as a sub stituted hydantoin. Contains 19% combined for maldehyde capable of liberation No. 1191 New alkaline scale and oxide remover for iron and steel is said to act electrolytically for rapid removal -without chemical attack. Recommended for plating lines and automatic equipment in volving alkaline solutions. No. 1192 A zirconium-copper alloy now available is re ported to combine high electrical conductivity with good strength retention at elevated temper atures. Suggested for electrical motor commu tators serving above 500°F where strength is needed. Conductivity is 95.8% of copper. No.1193 Fire protection for chemicals is discussed in a new 152-page book which can be purchased by those interested in the subject. Chemical hazards are analyzed, and methods of fire prevention and fire fighting are covered. No. 1194 A new cellulose derivative dissolves readily in cold water and is suggested for use as a thick ener, emulsifier, adhesive and binder. The mate rial is an ethyl-hydroxyethyl cellulose. Solutions are claimed to resist mold. No. 1195 A dye for photographic emulsions has just been synthesized which extends their sensitivity far into the infrared. Known as thiahexacaxbocyanine, the dye has its absorption maximum at 1140 millimicrons. No. 1196 Titanium wire cloth is now on the market in sizes from 60 mesh to coarser grades. It is re ported to be particularly suitable for filtering or screening highly corrosive materials. No. 1197 A new material for standardizing a d d s directly in one step is now available to laboratory workers. It is tris (hydroxymethyl)- amino-methane, re ported to eliminate the usual acid vs. base, base vs. phthalate procedure. No. 1198 Glycerine, its commercial grades, specifications, test methods, shipping and storage requirements, is described in a 19-page booklet just issued. A 17-page booklet on properties and uses of gly cerine is also available. No. 1199
