A process for the purification of organic auxiliary liquids |
| abstract |
A number of organic liquids are purified by treatment with ion exchangers alone or in conjunction with active carbon or aluminium oxide. Specification 943,177 is referred to.ALSO:Organic auxiliary liquids from the polymerization of formaldehyde are purified by contact with an acid and/or basic and/or a neutral ion exchanger. The liquids may be purified in a continuous manner and recycled to the formaldehyde polymerization which may include the steps of acylating or alkylating the polymer. Specification 913,177 is referred to. |
