    Abstract: Described is a process to synthesize nano-size Zeolite A from an amorphous gel precursor which can be synthesized via reaction of NaAlO2, NaOH, and tetraethoxysilane (TEOS). Zeolite A with particle sizes of ˜150 nm was made by transformation of the amorphous precursor in (CH3)4NOH solution with Zeolite A seeding. The nano-sized Zeolite A can be part of processes for making non-phosphate detergent where the as-synthesized Zeolite A used as builders, for making thin films for separation and/or catalysis, for making secondary ordered patterns.

    Abstract: A process for reversible sorption of sulfur trioxide onto a sorbent comprising a) contacting from about 15% to 100% sulfur trioxide with the sorbent under anhydrous conditions at a temperature of from about 35° C. to about 150° C. thereby sorbing the sulfur trioxide onto the sorbent, b) desorbing sulfur trioxide from the sorbent at a temperature of from about 150° C. to about 350° C. at about atmospheric pressure, or under a vacuum pressure, and c) recycling said sorbent by continuously repeating steps a) and b), wherein said sorbent consists essentially of silica or zeolite having a silicon to aluminum ratio in the ranges of from about 1 to about 4.4 or greater than about 5.1, and having a pore size of at least 0.5 nm is disclosed.

    Abstract: The present invention relates to an improved packaging composition comprising an ethylene copolymer selected from ethylene acid or ester copolymers such as ethylene vinyl acetate, ethylene/acrylic acid or methacrylic acid copolymers which optionally contain a third comonomer such as an alkyl acrylate and the corresponding ionomers of said copolymers which are blended with a hydrophilic zeolite to form a composition which removes residual acids or small esters from the polymeric or ionomeric composition containing such residual acids. The acids may be present as initial by products in the copolymerization process or may be degradation products. The use of these compositions is particularly important when the resins are formed into packages or other fabricated material which are exposed to acid sensitive material.
