    Abstract: Higher alcohols, useful as intermediates for surfactants, are produced in high yields at high conversion by paraffin oxidn. in process where orthoboric acid is introduced into initial 10-25 (esp. 12-15) C paraffin mixt. heated to >=170-175 degrees C. and dissolved under quick far-reaching dehydration. Paraffin oxidn. takes place for some time at same temp., by passing in O2-contng. gas mixtures, and is completed at 130-165 (esp. 150-155) degrees C. Pref. 5-10, esp. 5-6,% boric acid, w.r.t. paraffin, is used. Pref. induction period after dissolution of boric acid is 5-45, esp. 15-30, min. Pref. oxidising agent is N2 contng. 2-10, esp. 4-5, % O2, used in amts. of 400 l./hr./kg. of paraffin.
