Fatty alcohols from the oxidation products of solid waxes

1. Information has been obtained on the methanol extraction of unsaponifiables-II and on unsaponifiables-II fraction boiling below 425°C, in order to design a pilot plant for separating C10-C20 alcohols. 2. Additional results are obtained on the crystallization of a methanol extract of unsaponifiables-II and the unsaponifiables-II fraction boiling below 425°C, in batch mixers and for filtration on an experimental drum vacuum filter, with the purpose of removing the solid high molecular weight products. 3. The following yields of technical C10-C20 aliphatic alcohols have been obtained, calculated on unsaponifiables-II: 17.8% from unsaponifiables-II, 19.6% from the fraction boiling below 425°C. 4. After extracting the nonsulfated substance the technical C10-C16 alcohol fractions are good raw material for producing washing powders.
