✦ Synopsis

technology for synthesizing zeolites, using a structure directing agent which can be easily removed from the finished product. Existing zeolite production technology uses a structure-directing agent which remains in the product's pores. The researchers synthesized a ZSM-5 zeolite using a cyclical acetal structure directing agent obtained from a cyclical ketone/ethylene glycol reaction. The agent can be converted into ketone and ethylene glycol by reducing pH levels.

Ethyl acetate from ethanol

Davy Process Technology has developed an integrated process for making ethyl acetate from ethanol. Acetaldehyde is an intermediate and the product is purified by selective hydrogenation. The process was first demonstrated in May 2001.
