| 应用领域 | Uses: Used as a polymerization catalyst、also used in photography and in electrolyte solutions for storage batteries、[HSDB]、Battery Manufacturing [Category: Industry]、Photographic Processing [Category: Other]、Polyols are important raw materials for the production of polyurethane foams. Their synthesis profits from use of cesium hydroxide as base catalyst. In polyol synthesis isomerization of the starting material propylene oxide is an adverse side reaction eventually leading to chain termination in the polymerization with polyisocyanate. The tendency of polyols to undergo isomerization is minimized when using cesium hydroxide、as isomerization tendency decreases in the order Li > Na > K > Rb > Cs.、Recommended as electrolyte in alkaline storage batteries at subzero temperatures、polymerization catalyst for siloxanes.、Industry Uses: Intermediate、Methods of Manufacturing: Alkaline decomposition can be carried out either by mixing、powdered pollucite、ore with lime and calcium chloride and heating to 800 - 900 °C followed by leaching of the residue or by heating pollucite with sodium chloride and soda ash to 600 - 800 °C followed by leaching. Both processes furnish impure solutions of cesium chloride. Hydrothermal alkaline leaching with Ca(OH)2 at 200 - 280 °C under high pressure has been developed as an industrial process to yield a low-purity cesium hydroxide directly from pollucite.、By adding barium hydroxide to an aqueous solution of cesium sulfate.、Formulations、Preparations: Prepared by electrolysis of Cs salts、Grade: Technical、50% aqueous solution.、U.S. Production: 2023: <50、000 lb、2022: <50、2021: <50、2020: 50、000 - <250、General Manufacturing Information: All Other Basic Inorganic Chemical Manufacturing、Cesium hydroxide (Cs(OH)): ACTIVE、If cesium is exposed to air、explosion-like oxidation to form cesium superoxide ... occurs、contact with water results in a vigourous reaction to form cesium hydroxide and hydrogen gas、which may ignite spontaneously |
