| titleOfInvention | Method for the production of etherified urea-formaldehyde condensate |
| abstract | Method for the production of etherified urea-formaldehyde condensate bynetherification reaction of urea-formaldehyde condensate obtained in the condensation processn1 mole of urea with 2.2-2.4 moles of formaldehyde, in which etherification is carried outntechnical methanol or a mixture of technical methanol and distillate-methanol-waterntowards a catalytic system composed of a ion exchange resin in the hydrogen formnand a strong mineral acid, characterized in that the condensation process is carried out atnusing formalin at a concentration greater than 40%, preferably 42-50%, versus 10-15% ethylene glycolnor diethylene based on the total amount of urea and formalinnused for the condensation reaction or mono-, diethylene glycol in an amount of 10-15%ninto the reaction medium after the condensation process is completed, at a temperature not lower thann75 ° C, then 5-10 moles of methanol in the form of a technical product are added to the condensationnor a mixture of technical methanol and methanol distillate and carry out etherification innknown way. |
