Title: Process of and apparatus for preparing dinitrogen pentoxide
IPC: C01B21/20
Filed: 1991-07-30
Abstract: PCT No. PCT/GB91/01250 Sec. 371 Date Apr. 17, 1992 Sec. 102(e) Date Apr. 17, 1992 PCT Filed Jul. 25, 1991 PCT Pub. No. WO92/02452 PCT Pub. Date Feb. 20, 1992.Process for producing dinitrogen pentoxide (N2O5) consists of reacting a solution of dinitrogen tetroxide (N2O4) in a volatile organic solvent, with a stream of an ozone-containing carrier gas. N2O5 produced by reaction between the N2O4 and ozone is transferred into the gas stream, and is thereafter condensed out of the gas stream by contact with further inert organic solvent. The latent heat of formation of N2O5 is absorbed by the heat of vaporization of the solvent, so limiting increases in reaction temperature and suppressing the dissociation of the N2O5. In a preferred embodiment the reaction and absorption steps are performed in separate columns having organic solvent recalculating continuously through each with carrier gas flowing continuously from the reaction column to the absorption column.

Title: Purification of polyisocyanate composition
Inventor: ASAHINA YOSHIYUKI
IPC: C08G18/82
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To purify a mixture containing at least a diisocyanate monomer and a polyisocyanate composition while preventing the recovered diisocyanate monomer from being contaminated with the polyisocyanate composition by deaerating the mixture and feeding the deaerated mixture into a thin-film evaporator to separate the polyisocyanate composition from the mixture. SOLUTION: When a low-boiling component such as a diisocyanate monomer is evaporated from a mixture containing a polyisocyanate composition and a diisocyanate monomer by using a thin-film evaporator of e.g. a scrape type to obtain the polyisocyanate composition, entrainment raises the contamination of the separated low-boiling components with the polyisocyanate composition being a high-boiling component as the amount of the mixture fed into the evaporator increases. Especially, in the case of a polyisocyanate composition produced by using an agent for biuret formation such as water and accompanied by the formation of by-product gases such as carbon dioxide, the entrainment is remarkable. In order to prevent the entrainment, the mixture is deaerated before being fed into the evaporator.
