The invention relates to novel crystalline phases of 5,6-dichloro-2-(isopropylamino)-1-(?-L-ribofuranosyl)-1H-benzimidazole (Maribavir), pharmaceutical compositions thereof and their use in medical therapy.

A method for forming a blend of ethers from a blend of alcohols includes a step of reacting a hydrocarbon-containing gas with an oxygen-containing gas to form first product blend. The first product blend includes a blend of partially oxygenated compounds. The blend of partially oxygenated compounds is provided to a reactive distillation station where it is converted a second product blend. The second product blend typically includes a mixture of ethers. An apparatus implementing the method is also provided.

A process for dehydration of an ethanol feedstock to ethylene by: a) preheating ethanol feedstock by heat exchange with effluent from e), b) pretreating the ethanol feedstock to produce pretreated ethanol feedstock, c) vaporizing a vaporization feedstock containing pretreated ethanol feedstock and at least a portion of the flow of treated water recycled in an exchanger to produce a vaporized feedstock, d) compressing said vaporized feedstock to produce a compressed feedstock, e) dehydrating said compressed feedstock in at least one adiabatic reactor, f) separating the effluent from the last adiabatic reactor of e) into an effluent containing ethylene and an effluent containing water, g) purifying at least a portion of the effluent containing water from 0 and separating at least one flow of treated water and at least one flow of unconverted ethanol, h) recycling at least a portion of the flow of treated water from g) upstream of c).
