Title: Improvements in and relating to the production of esters
Inventor: DEAN FRED
IPC: C07C69/80
Filed: 1960-06-22
Abstract: In a process for the production of colourless esters an alcohol is reacted with a carboxylic acid or anhydride thereof in the presence of a salt containing a polyvalent metal in a lower valency state, the salt having a greater affinity for oxygen than that possessed by any oxidisable colour-forming impurities in the reaction mixture and being insufficiently active to catalyse the oxidation of the impurities. The metal may be copper, iron, tin or chromium, and examples of salts are cuprous chloride, ferrous sulphate and stannous sulphate; the amount of salt may be up to 10% by weight of the reactants.  The acid may be an aliphatic or aromatic mono- or di-carboxylic acid (examples are adipic, sebacic, benzoic and phthalic acids), and the alcohol may be mono- or di-hydric (examples are iso-hexanol, 2-ethyl-hexanol, nonanol and ethylene glycol). Sulphuric acid or para-toluene sulphonic acid may be used as catalyst, and an entrainer, e.g. toluene, may be present.  In Examples C7 to C9 oxo alcohols are esterified with phthalic anhydride in the presence of cuprous chloride, ferrous sulphate and stannous sulphate.

Elongated loops of pile yarn are drawn during a stitch forming sequence and are held drawn until completion of the holding stitches when tension is released and the bight ends of the pile loops are crush cut to form an even pile. As shown, a pile fabric 10 is knitted using cylinder needles 15 and sinkers 20, alternate sinkers 20B, 20D moving inwards further than the intervening sinkers 20A, 20C. The pile yarn 25, caught in the hooks of needles 16, loops over the lower surfaces 22 of sinkers 20A and 20C and the upper noses 21 of sinkers 20B and 20C. The body yarn 30 and pile yarn 25 are drawn through stitches 12 by needles 15 and the loops engage noses 21 forming pile loops 13, which are engaged by a spring biased rotating crushing wheel 40 and severed without tensioning the yarn. Alternatively, the pile loop may be held by dial needles and may be crushed against the dial edge by a driven wheel, either the dial edge or the wheel having a sharp edge.
