Opis produkcji związków oksyetylenowanych:
Alcohols, fatty acids, nonyphenol etc are mixed in mixers and batch reactors with NaOH catalyst. On the second phase ethylene and propylene oxides are fed into the batch. This causes an exothermic oxidation reaction, which requires constant cooling. The reaction is killed with a neutralisation agent and the solution is let to STANDARDIZE.
Drugi opis dotyczy produkcji pochodnych naftalenu:
Process is based on sulphonation of naphthalene under nitrogen blanketing. The reaction occurs in a batch reactor in atmospheric pressure and requires heating by steam. After condensation (water and formalin added), neutralisation by NaOH and Ca2OH, filtration and STANDARDISATION with NaOH the products are stored in tanks.
