Abstract
(EN) The present invention addresses the problem of providing a method for efficiently removing water contained in pentafluoropropane. Provided as a solution to the problem is a method including a step in which a composition containing pentafluoropropane and water is distilled, and as a result thereof, pentafluoropropane having a higher water concentration than said composition is extracted as a first stream, and pentafluoropropane having a lower water concentration than said composition is extracted as a second stream.
(FR) Le problème à la base de la présente invention concerne un procédé efficace d'élimination de l'eau contenue dans du pentafluoropropane. La solution de l'invention porte sur un procédé comprenant une étape dans laquelle une composition contenant du pentafluoropropane et de l'eau est distillée et, par conséquent, du pentafluoropropane présentant une concentration en eau supérieure à celle de ladite composition est extrait sous la forme d'un premier flux et du pentafluoropropane présentant une concentration en eau inférieure à celle de ladite composition est extrait sous la forme d'un deuxième flux.
(JA) ペンタフルオロプロパンに含まれる水分を効率よく除去できる方法を提供することを課題とする。解決手段として、ペンタフルオロプロパン及び水を含む組成物を蒸留することにより、該組成物より水分濃度の高いペンタフルオロプロパンを第1ストリームとして、該組成物より水分濃度の低いペンタフルオロプロパンを第2ストリームとして、それぞれ抜き出す工程を含む方法を提供する。
