It's yours for the asking . . . from Brooks Here is a quick, convenient way to compare rotameter specifica tions to find the correct model for any particular application. With the Brooks Rotameter Selection Guide, you can deter mine essential information at a glance. You simply set the chart dial at the required flow range, and other pertinent data—model, size, maximum operating temper ature and pressure — are con veniently presented. The Guide covers the full line of Brooks Rotameters . . . a line that includes everything from rugged armored meters for large flows, high temperatures and pres sures, to "miniature" purge meters for small flow indication. All in all, you'll find the Selec tion Guide a genuinely useful reference manual. To get a copy, request Bulletin 110.

International TO SELL THEIR PRODUCTS ABROAD It's easy to understand why. The European and foreign chemical industry is growing just about as fast as it is able to. The only limiting factor is in the ability of its chemists and chemical engineers to design and build plants fast enough. Thus the demand for the latest in chemical processing tech nology is acute. There is only one complete technical publication in the chemical field; INDUSTRIAL AND ENGINEERING CHEMISTRY. Technical management men throughout the world rely on it for the latest in process technology. That's why I/EC has the largest international circula tion of any technical publica tion in the field. And that's why over 100 companies are using I/EC—International to sell their products abroad. I/EC can help you solve your international marketing prob lems.

Du Pont
DIMETHYLACETAMIDE in commercial quantities This highly polar alkyl amide is both a versatile solvent and a reaction catalyst A s a Catalyst and S o l v e n t f o r Reactions Like other alkyl carboxylic amides, Du Pont Dimethylacetamide (DMAC) has the unusual ability to serve as a reaction catalyst. It can convert molecules into reactive forms by solvation and high dielectric effect. Reactions improved by the use of Du Pont DMAC include: elimination reactions; halogenations; cyclization; alkylations; interesterification; hydrocyanations; preparation of nitriles; and preparation of organic acid chlorides.
A s a General S o l v e n t Du Pont DMAC is an excellent solvent for synthetic polymers, natu ral gums and resins. Because it is highly polar, dimethylacetamide has been found particularly useful as a solvent for polyacrylonitrile, its co-polymers, and inter-polymers. The unique solvent power of DMAC makes it a valuable chemical for use in a number of applica tions, including crystallization and purification solvent, non-aqueous electrolytic solvent and paint remover. FURTHER DATA on Du Pont DMAC—its physical and chemical prop erties and other uses—are outlined in the new Product Information Bulletin prepared by Du Pont. For your copy, just mail the coupon.

Any i d e a s in these Silicate Reactions'? When PQ Sodium Silicate is mixed with acid or acidic compounds, you quickly see a typical reaction—the silica is released. Depending on concentration and temperature, silica precipitates as a floe, or as a lumpy mass or as a gel. Many uses of the soluble silicates spring from combinations with other chemicals. Take for instance: Sodium Silicate P L U S . . . ammonium sulfate = silica sol magnesium salts = complex magnesium silicates aluminum salts = complex aluminum silicate iron oxide = iron silicate—silica complex zinc oxide = complex insoluble silicate The coupon below is for your convenience in requesting additional information or samples.
