Embodiments provide a process for purifying an alkylene oxide composition, which comprises (1) obtaining a crude alkylene oxide composition comprising an ionic component; (2) passing the crude alkylene oxide composition through a molecular sieve; and (3) obtaining a purified alkylene oxide composition. A purified alkylene oxide composition suitable for a subsequent process can be obtained.

A system for recovering a sterilization agent may include a pressure reducing valve for reducing a pressure of a waste gas from a sterilization chamber to a first predefined pressure. The waste gas may include a gaseous mixture of a sterilization agent, nitrogen gas, and water vapor. A first condenser may cool the gaseous mixture to below a boiling point temperature and above a freezing point temperature of the water vapor at the first predefined pressure. A first tank may store the condensed water vapor. A separation pump may raise the pressure of the gaseous mixture to a second predefined pressure. A second condenser may cool the gaseous mixture to below a boiling point temperature and above a freezing point temperature of the sterilization agent at the second predefined pressure causing the sterilization agent to condense into a liquid. A second tank may store the separated sterilization agent.

Disclosed are gas-phase ODH and OCP processes for converting alkanes (e.g., C.sub.2H.sub.6 and C.sub.3H.sub.8) to alkenes (e.g., C.sub.2H.sub.4 and C.sub.3H.sub.6) or oxygenates (e.g., methanol, ethanol, isopropanol, or propylene oxide) or converting alkenes (e.g., ethylene and propene) and oxygenates (e.g., methanol, ethanol, isopropanol or propylene oxide) to longer carbon-chain alkenes or longer carbon-chain alkanes with or without solid catalysts.

The present invention relates to a method for oxidizing beta-caryophyllene with oxygen, in particular atmospheric oxygen, which avoids the use of catalysts, enzymes and solvents. Furthermore, the present invention provides a mixture comprising certain caryophyllene oxides as well as their use as a flavor and/or fragrance. The present invention also relates to products and semi-finished products comprising the mixture according to the invention.

An intermediate compound is prepared and used for the synthesis of halichondrin B, eribulin or an analog thereof, particularly a structural fragment C27-C35 thereof. The starting materials of the synthetic route are readily available, and the optical purity of the starting materials can be ensured, so that the optical purity of the structural fragment C27-C35 in halichondrin B, eribulin or the analog thereof is ensured. Steps for constructing a chiral center of the structural fragment C27-C35 feature higher diastereoselectivity and yield, in particular preparation methods of compounds of formulae (X), (XI), (XVI) and (XV). By-products of partial reactions can be removed only by recrystallization, which results in easy purification and significant reduce in cost.
