Amberlyst 15 wet -- technical data sheet

AMBERLYST™ 15WET Industrial Grade Strongly Acidic Catalyst
For Catalysis and Separation technologies

AMBERLYST 15WET is a strongly acidic, sulfonic acid, macroreticular polymeric resin based on crosslinked styrene divinylbenzene copolymers. Its continuous open pore structure and excellent physical, thermal and chemical stability makes it the resin of choice in many applications. It also possesses a greater resistance to oxidants such as chlorine, oxygen and chromates than most other polymeric resins. AMBERLYST 15WET can be used directly in aqueous systems or in organic media after conditioning with a water miscible solvent. Typical Properties
These properties are typical but do not constitute specifications.
Physical form
[1] Contractual value Test methods are available on request. Catalysis
AMBERLYST 15WET is used in a wide variety of organic reactions. It has the optimal balance of surface area, acid capacity, activity and pore diameter to make it the catalyst of choice for etherification (MTBE, ETBE, TAME), esteri-fication and hydration reactions. Its optimized pore size distribution makes it an excellent catalyst when fouling is anticipated. Suggested Operating Conditions
Maximum operating temperature
* 1 BV = 1 m3 solution per m3 of resin Separation Technologies
AMBERLYST 15WET can be used for processes where ionic or organic impurities have to be removed or recovered from a process liquor. Both cationic and anionic compounds can be removed through either ionic and adsorptive interactions of the polymer and its acidic groups with the impurity. Its excellent resistance against oxidation makes it a superior resin in many applications. Suggested Operating Conditions
pH range
Maximum operating temperature 120 °C (250 °F) Minimum bed depth Regenerants
2 BV (15 gal/ft3) at regeneration flow rate 2 to 4 BV (15 to 30 gal/ft3 ) at service flow rate Hydraulic Characteristics
Figure 1 shows the bed expansion of AMBERLYST 15WET as a function of backwash flow rate and water temperature. Figure 2 shows the pressure drop data for AMBERLYST 15WET as a function of service flow rate and water temperature. All our products are produced in ISO 9002 certified manufacturing facilities. AMBERLYST is a trademark of Rohm and Haas Company, Philadelphia, U.S.A. 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.
