Abstract: Very pure 1,6-hexanediol is obtd. from a mixt. with other diols by opt. distilling out the light and heavy fractions and partially crystallising out crude alcohol mixt. by cooling to 42-15 degrees C, followed by sepn. of the crystals, washing with 1,6-hexanediol and recycling of the mother liquor obtd. after sepn. of the crystals to the crude alcohol mixt. prior to its distn. Purity is >99% as reqd. in the prepn. of plastics and esp. fibres.

Abstract: Aminoalkanol sulphuric acids, i.e. sulphuric acid monoesters of aminoalkanols are prepared by allowing an aminoalkanol and sulphuric acid to flow into a vigorously stirred suspension agent which agent is immiscible with water and is kept boiling at 70 DEG to 150 DEG C., the water formed in the reaction and any water supplied with the reactants being distilled off together with part of the suspension agent, the reaction being effected at atmospheric or subatmospheric pressure.
