Unformatted text preview: AMBERLYST® 15WET Industrial Grade Strongly Acidic Catalyst PRODUCT DATA SHEET AMBERLYST 15WET is a macroreticular, strongly acidic, polymeric catalyst. Its continuous open pore structure makes it an excellent heterogeneous acid catalyst for a wide variety of organic reactions. AMBERLYST 15WET catalysts' polymeric structure is extremely resistant to breakdown by osmotic, mechanical and thermal shock. It also possesses greater resistance to oxidants such as chloride, oxygen and chromates than most other polymeric catalysts. AMBERLYST 15WET can be used directly in aqueous systems or in organic media after conditioning with a water miscible Remove banner solvent. AMBERLYST 15WET has the optimal balance of surface area, acid capacity and pore diameter to make it the catalyst of choice for etherification (MTBE, ETBE, TAME), esterification and hydration reactions. AMBERLYST 15WET can also be used for chemical processing applications to remove impurities (metal ions) and basic organic compounds (amines, etc.) from aqueous and non aqueous environments (appropriate pretreatment required).

Ion exchange resins and polymeric adsorbents, as produced, contain by-products resulting from the manufacturing process. The user must determine the extent to which organic by-products must be removed for any particular use and establish techniques to assure that the appropriate level of purity is achieved for that use. The user must ensure compliance with all prudent safety standards and regulatory requirements governing the application. Except where specifically otherwise stated, Rohm and Haas Company does not recommend its ion exchange resins or polymeric adsorbents, as supplied, as being suitable or appropriately pure for any particular use. Consult your Rohm and Haas technical representative for further information. Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Nitric acid and other strong oxidising agents can cause explosive type reactions when mixed with Ion Exchange resins. Proper design of process equipment to prevent rapid buildup of pressure is necessary if use of an oxidising agent such as nitric acid is contemplated. Before using strong oxidising agents in contact with Ion Exchange Resins, consult sources knowledgeable in the handling of these materials. Rohm and Haas Company makes no warranties either expressed or implied as to the accuracy of appropriateness of this data and expressly excludes any liability upon Rohm and Haas arising out of its use. We recommend that the prospective users determine for themselves the suitability of Rohm and Haas materials and suggestions for any use prior to their adoption. Suggestions for uses of our products of the inclusion of descriptive material from patents and the citation of specific patents in this publication should not be understood as recommending the use of our products in violation of any patent or as permission or license to use any patents of the Rohm and Haas Company.
