Description

Известно использование фенольных смол при обесфеноливании над.смольных вод, образующихс  при ироизводстве феноло-формальдегидных смол, где выделенна  смола исиользуетс  дл  приготовлени  древесно-стружечных плит в строительстве. Другие известные способы привод т к образованию смол дл  разных технических целей, однако нет данных об использовании смол, образующихс  при обесфеноливании надсмольных вод, дл  получени  ионообменных смол.It is known the use of phenolic resins in the process of dephenolization of tar water formed during the production of phenol-formaldehyde resins, where the isolated resin is used for the preparation of chipboard in construction. Other known methods lead to the formation of resins for various technical purposes; however, there is no data on the use of resins formed in the dephenolization of supra-resin waters to obtain ion-exchange resins.

Предлагаетс  способ получени  слабокислотных карбоксилсодержащих катионов, как ценной ионообменной смолы из продуктов, содержащихс  в надсмолыных водах - отходах в производстве феноло-формальдегидных смол.A method is proposed for the preparation of weakly acidic carboxyl-containing cations, as a valuable ion-exchange resin from products contained in supra-resin water - waste from the production of phenol-formaldehyde resins.

Предлагаемый способ получени  слабокислотных ионообменников представл ет технический интерес, так как он может заменить катионит КБ-5, получаемый в насто щее врем  из остродефицитного резорцинаТехнические характеристики катионита, получаемого по предлалаемому способу, достаточно удовлетворительны.The proposed method for the preparation of weakly acidic ion exchangers is of technical interest, since it can replace the CB-5 cation exchanger, which is currently being obtained from extremely deficient resorcin.

Катионит из водорастворимой смолы получают следующим путем.The cation resin from the water-soluble resin is obtained in the following way.

Смолу эмульгируют в масл ной среде, где npi нагревании она переходит в гель. Не отвержденные гранулы обрабатываю г хлорацетатом натри  или хлоруксусной кислотой. После этого гранулы дополнительно бакелизируют, отмывают от масла и высущивают.The resin is emulsified in an oily medium, where it is heated by npi to gel. Uncured granules are treated with sodium chloroacetate or chloroacetic acid. After that, the granules are additionally bakelized, washed from the oil and dried.

Прел.мет изобретени Subject Invention

Способ получени  слабокислых карбоксилсодержащих катионитов, отличающийс  тем, что, с целью удещевлени  стоимости конечного продукта, фенол-формальдегидную смолу эмульгируют в масл ной среде и обрабатывают хлорацетатом натри  и хлоруксусной кислотой.A method for producing weakly acidic carboxyl-containing cation exchangers, characterized in that, in order to increase the cost of the final product, the phenol-formaldehyde resin is emulsified in an oil medium and treated with sodium chloroacetate and chloroacetic acid.
