Description
Изобретение относитс к способам окислени сульфита. Известел способ окислени сульфита кислородом воздуха в водном ipa.CTBOpe в присутствии сульфита .меди. Недостатком известного способа вл етс невысока скорость окислени сульфита. По предлагаемому способу троцесс осуществл ют в Присутствии медно-аммиачного комплекса. Такой катализатор обладает высокой а-ктивностью и позвол ет значительно интенсифи|Цирсвать лроцесс. Та.к, в течение 1 мин в присутствии ;медко-а,ммиач:НО:Го комплекса успевает прореаги ровать 12,5 г, в то врем «ак в известном способе за это же врем уопевает прореагировать только 2,5 г. Пример. В реа:ктор, снабженный мешалкой и устройством дл подачи воздуха, заливают раствор сульфита натри с ко:нпентрацией 25 г/л, содержащий раствор CuSOi в количестве 8 мл раствора (35 г л) на 1 л раствора сульфита. Процесс окислени провод т при высоких значени х коэффициента массоотдачи. Аналогично осуществл ют опыт окислени сульфита с применением меди в виде аммиачного комплекса. Значени времени, соответствующего различной степени превращени при разных катализаторах , приведены в . Врем , в мин, при степени превращени , в %: Врем 50%-ного превращени с медно-ам3 5 раз. миачным комплексом сокращаетс Предмет изобретени Способ окислени сульфита в растворе кислородом в присутствии соединений меди, отличающийс тем, что, с целью интенсификации процесса, в качестве соединени меди примен ют медно-аммиачный комплекс.This invention relates to methods for the oxidation of sulfite. A known method of oxidation of sulfite with oxygen in air in water ipa.CTBOpe in the presence of sulfite. The disadvantage of this method is the low rate of oxidation of sulfite. According to the proposed method, the trotses are carried out in the Presence of a copper-ammonia complex. Such a catalyst possesses high a-ktivnost and allows significantly intensification of the process. Thus, for 1 min in the presence of; medical-a, mmiich: BUT: Go of the complex has time to respond to 12.5 g, while “in the known method for the same time only 2.5 g can react. Example . In a pea: ktor equipped with an agitator and an air supply device, pour sodium sulfite solution with a concentration of 25 g / l, containing a solution of CuSOi in an amount of 8 ml (35 g l) per 1 l of sulfite solution. The oxidation process is carried out at high values of the mass transfer coefficient. Similarly, the experience of sulfite oxidation is carried out using copper in the form of an ammonia complex. Values of time corresponding to different degrees of conversion under different catalysts are given in c. Time, per minute, with a degree of conversion, in%: Time of 50% conversion with copper 3 3 times. The complex is reduced. Subject of the invention. A method for oxidizing sulfite in solution with oxygen in the presence of copper compounds, characterized in that, in order to intensify the process, the copper-ammonia complex is used as the copper compound.
