The main groups of compounds covered by this heading are : (1) Aluminates. Derivatives of aluminium hydroxide. (a) Sodium aluminate. Obtained by treating bauxite with sodium hydroxide solution. Occurs as a white powder soluble in water, in aqueous solutions or in paste form. Used as a mordant in dyeing (alkaline mordant); in the preparation of lakes; for sizing paper; as a filler for soap; for hardening plaster; for manufacturing opaque glass; for purifying industrial water, etc. (b) Potassium aluminate. Prepared by dissolving bauxite in potassium hydroxide. White, micro-crystalline masses, hygroscopic and soluble in water. Same uses as sodium aluminate. (c) Calcium aluminate. Obtained by the fusion of bauxite and calcium oxide in an electric furnace; white powder, insoluble in water. Used in dyeing (mordant); for purifying industrial water (ion exchanger); in paper-making (sizing); in the manufacture of glass, soap, special cements, polishing preparations and other aluminates. (d) Chromium aluminate. Obtained by heating a mixture of aluminium oxide, calcium fluoride and ammonium dichromate. Ceramic colour. (e) Cobalt aluminate. Prepared from sodium aluminate and a cobalt salt. It constitutes, either pure or mixed with aluminium oxide, cobalt blue (Thenard’s blue). Used in the preparation of cerulean blue (with zinc aluminate), azure blue, smalt blue, Saxony blue, Sèvres blue, etc.

This document has gone through review process within the Agency and is cleared for publication. Mention of trade names or commercial products does not constitute endorsement or recommendation for use. Abt Associates Report Title Insert Date ▌1 EXECUTIVE SUMMARY Executive Summary EPA is releasing an updated version of the SPECIATE database, SPECIATE 5.1, about a year after the release of SPECIATE 5.0. In lieu of full documentation, this document provides highlights of the revisions to SPECIATE 5.0. Full documentation of the SPECIATE program can be found in the SPECIATE documentation section of EPA’s air emissions modeling website. SPECIATE is the U.S. Environmental Protection Agency’s (EPA) repository of speciation profiles of air pollution sources that provide the species makeup or composition of organic gas, particulate matter (PM) and other pollutants emitted from these sources. Some of the many uses of these source profiles include: (1) creating speciated emissions inventories for regional haze, PM, greenhouse gas (GHG), and photochemical air quality modeling; (2) adding PM species in the EPA’s National Emissions Inventory (NEI); (3) developing black carbon assessments and particulate carbonaceous inventories; (4) estimating air toxic pollutant emissions from PM and organic gas primary emissions; (5) providing input to chemical mass balance (CMB) receptor models; and, (6) verifying profiles derived from ambient measurements by multivariate receptor models (e.g., factor analysis and positive matrix factorization).

It is commolzly stated,in the text books, that caustic soda and caustic potash dissolve aluminium with the evolution of hydrogen and formatiol1 of all1mil1ates. A number of alurninates have been obtailzed by treating the oxide or hydroxide of aluminillln with alkalies either in solutio!! or in the fused state. Thus Unverdorben :# gives all aCCOlult of the preparation of potassium aluminate by treating aluminium with a solution of caustic potash. He says that the solution saturates itself almost completely, though there always remains some free potash. He separates this from the aluminate by washing with alchol after evaporating to dryness. No data were given but he claims the compound contained.

C. WASHINGTON GOVERNMENT PRINTING OFFiCE 1924 SUMMARY OF TECHNICAL METHODS FOR THE UTILI¬ ZATION OF MOLASSES. COLLATED FROM PATENT LITERATURE. ABSTRACT. Economic conditions the world over have made it generally recognized that the future of the American beet-sugar industry is to a great extent dependent on the profitable utilization of the molasses produced. The latter contains numerous val¬ uable substances which have never been successfully recovered outside of Germany. For many years that country has seen fit to veil its developments and discoveries and to maintain the strictest secrecy regarding the operation of its molasses plants. The scientific literature on the subject is practically barren, so far as the actual results achieved in Germany are concerned. In order to carry out the necessary experi¬ mental work for the American industry every possible source of information has been investigated. After a few clues were obtained the United States Patent Office liter¬ ature was searched and eventually over 1,000 German patents on molasses utilization and associated subjects were uncovered.

Manchester M3 3JY (GB) 2621 E. 46th Street Tulsa, Oklahoma 74105 (US) © Processes of producing potassium fluoroaluminates. (57) Potassium tetrafluoroaluminate and potassium hexafluoroaluminate have been produced by three new processes : (a) by reacting alumina trihydrate with freshly produced, hot, solvated potassium fluoride solution in presence of stoichiometric amounts and/or an excess of hydrogen fluoride, or (b) by reacting aluminum trifluoride trihydrate with hot aqueous solution of potassium fluoride or potassium bifluoride, or (c) by generating in situ potassium aluminate by reacting alumina trihydrate with hot aqueous potassium hydroxide and treating the same with aqueous or anhydrous hydrogen fluoride.
