Description
При производстве сополимера СГ-1 на основе метакриловой кислоты и полиэфира ТГМ-3 в 20%-ном растворе поваренной соли выдел ютс пары метакриловой кислоты.In the production of methacrylic acid based on SG-1 copolymer and TGM-3 polyester, methacrylic acid vapor is released in a 20% solution of sodium chloride.
Описываемый способ позвол ет улавливать метакриловую кислоту из газов в количестве до 98%. С этой целью газы промывают в иолой башне 20%-ным раствором поваренной соли при 20-25° и сконденсировавшуюс кислоту отдел ют от раствора соли известным образом, например путем отстаивани . Такой способ может быть применен и в других производствах, где вырабатываетс или используетс метакрилова кислота.The described method makes it possible to capture methacrylic acid from gases in an amount up to 98%. To this end, the gases are washed in the Iol tower with a 20% solution of sodium chloride at 20–25 ° and the condensed acid is separated from the salt solution in a known manner, for example, by settling. This method can also be applied in other industries where methacrylic acid is produced or used.
На чертеже изображена технологическа схема производства сополимера СГ-1 с улавливанием метакриловой кислоты по описываемому способу.The drawing shows the technological scheme of production of the copolymer SG-1 with methacrylic acid trapping by the described method.
Основной процесс - синтез сополимера СГ-1 - проводитс в реакторе /. Выдел ющиес из реакционной смеси пары метакриловой кислоты поступают в буферную емкость 2, затем - в полую фарфоровую башню 3. Сверху башн орошаетс 20%-ным раствором поваренной соли при температуре 20-50°, регулируемой холодильником 4. Сконденсировавша с метакрилова кислота вместе с раствором поваренной соли поступает в буферную емкость 2, а из нее - в сборник 5, где собираетс в верхнем слое. Раствор поваренной соли (нижний слой) подаетс насосом 6 на орошение башни 3. После проведени дес ти операций все количество уловленной кислоты подаетс тем же насосом в реактор / дл получени сополимера.The main process — synthesis of the SG-1 copolymer — is carried out in a reactor. Methacrylic acid vapors released from the reaction mixture enter buffer chamber 2, then into hollow porcelain tower 3. From above, the tower is irrigated with 20% sodium chloride solution at a temperature of 20-50 ° controlled by a refrigerator 4. Condensed with methacrylic acid together with a solution salt enters the buffer tank 2, and from it into the collection 5, where it is collected in the upper layer. The salt solution (bottom layer) is fed by pump 6 to the tower 3 irrigation. After carrying out ten operations, the entire amount of trapped acid is fed by the same pump to the reactor / to obtain a copolymer.
Способ улавливани метакриловой кислоты из газов, отличаюш . и и с тем, что газы промывают в полой башне 20%-ным раствором поваренной соли при 20-50° и сконденсировавшуюс кислоту отдел ют от раствора соли известным образом, например путем отстаивани .The method for trapping methacrylic acid from gases is different. and with the fact that the gases are washed in the hollow tower with a 20% sodium chloride solution at 20-50 ° and the condensed acid is separated from the salt solution in a known manner, for example, by settling.
