Description

Образующиес  в процессе парофазного декарбонилировани  фурфурола контактные газы, содержащие фуран, водород и углекислоту, обычно направл ютс  непосредственно на дальнейшее гидрирование , с целью получени  тетрагидрофура га , а сам фуран,  вл ющийс  весьма .1етучим, плохо конденсируемым соединением, не выде.т етс  КЗ газовой смеси. Така  схема оправдана в тех случа х, когда тетрагидрофуран нредстав.л ет собой основной промежуточный нродукт в дальнейших химических превраш,ени х , например, дл  получени  бутадиена , бутандиола-1,4 и др. Однако дл  производства некоторых лекарственных препаратов необходим фуран или его раствор в инертном растворите,1е.Contact gases, containing furan, hydrogen and carbonic acid, formed during the vapor-phase decarbonylation of furfural, are usually sent directly to further hydrogenation, with the aim of obtaining tetrahydrofuran, and the furan itself, which is a very volatile, poorly condensable compound, does not emit short-circuiting gas mixture. Such a scheme is justified in cases where tetrahydrofuran is the main intermediate product in further chemical transformations, for example, to produce butadiene, 1,4-butanediol, etc. However, for the production of certain drugs, furan or its solution in inert dissolve, 1e.

Известные способы выделени  фурана из контактных газов парофазного декарбонилировани  фурфурола  в.ч ютс  мало рентабельными, так как требуют применени  дорогосто ших охлаждающих устройств и.)1и адсорбентов, нуждающихс  в посто нной регенерации.The known methods for separating furan from contact gases of vapor-phase decarbonylation of furfural are not very cost-effective, since they require the use of expensive cooling devices and.) 1 and adsorbents that need constant regeneration.

Предлагаемый способ выделени  фурапа по сравнению с известными  вл етс  наиболее простым и экономически целесообразным и осуществл етс  с применением обычного типа скруббера, вместо компрессорных установок г.Пбокого охлаждени  до минус 60.The proposed method of separating furap in comparison with the known ones is the simplest and most economically feasible and is carried out using the usual type of scrubber, instead of compressor units of the city of Bubble cooling to minus 60.

Особенность предлагаемого способа зак.почаетс  в том, что газы пропускают через органический растворитель , например толуол, из которого фуран выде.ч ют обычными способами, например, разгонкой.The peculiarity of the proposed method is that the gases are passed through an organic solvent, for example toluene, from which furan is extracted by conventional methods, for example, by distillation.

Технологический процесс выделени  фурана сводитс , таким обра- зом, к двум простьпг операци м; у.авливанию фурана при атмосферном давлении н ком 1атной температуре путем барботированн  контактных газов через толуол и последующей отгонке фурана из раствора толуола. После отгонки фурана толуол используетс  повторно.The furan extraction process is thus reduced to two simple steps; Suppressing furan at atmospheric pressure at a nominal temperature by sparging contact gases through toluene and then distilling the furan from a solution of toluene. After distilling the furan, toluene is reused.
