Definitions

  • This invention relates to improvements in amylase preparations.
  • amylases It is known practice to use for technical purposes. especially ior desizing, amylases. These enzymes are very sensitive towards salts of heavy metals, particularly those of copper and zinc. Even the traces of such metal salts which frequently occur in town water supplies may considerably aflect the action of an enzyme liquor prepared with the water. In the technical application of the amylases there arise considerable disturbances through heavy metals. Such disturbances are especially noteworthy when the amylases are used for removing sizes which contain copper or zinc salts, which is frequently the case since. such metallic salts are often added to the sizing solution to avoid fermentation and.
  • salts of the imino-diacetic acid or its substitution products of which the cation does not itself have an injurious action on the amylase must be used, but obviously only such salts of the imino-diacetic acid or its substitution products of which the cation does not itself have an injurious action on the amylase.
  • the salts used must be soluble in water. Itis generally sufllcient, however, if the salts are only slightly soluble in water, since the heavy metal compounds which are to be rendered harmless'by the salts are present in the desizing liquor for the most part only in small proportions. There follows a list of compounds which may be used in the invention:
  • CHI-COOR- (trimothylaniino-a:a':a-trimrboxylic acid) C H1.
  • C O O H CHaC O OH 7 iminodiacetic acid C III.
  • C O O H N-methyl-iminodiacetic acid 'HOOCJIIC CHLCOOH V N- CHz-CHrN H nooclnc CHaCOOH ethylenediamine-tetrsacetic acid V I I cracoon N-CHi.
  • C O OH JtHu C-hexyl-trime thylamino-a, a, a"-tricarboxylic acid CH.
  • C-plienyl-trimothyhmim a, a"-tricarboxylic acid
  • ethylenetriaminoacetic acids which are obtained by the reaction of diethylenetriamine with chloracetic acid.
  • the aforesaid compounds surpass to a considerable degree the protective agents hitherto added to enzyme preparations; They afford a practically complete protection also, which even remains when the temperature is raised.
  • the compounds do not yield with lime salts any disturbing precipitation and are also efiective in very hard Water. They form, for example when used as their salts, mixtures with enzyme preparations that are good durable commercial products; unlike other protective agents they are equal in their effect towards different metals, for example zinc and copper.
  • the protective action of the substances in question is available for amylases of any origin, for example in the case of pancreas amylases or bacterial amylases.
  • a protective agent is preferably added, for example in the form of its alkali salt, to the amylase preparation during the manufacture of the latter.
  • the enzyme preparation may also receive otherwise usualadditions such as hufler substances, stabilising agents and the like.
  • a desizing agent of very good effect which is insensitive to the traces of-copper and zinc presentinthe usual'town water supply, is obtained by mixing 5 parts by weight of dry pancreas (Willstfitter and; Waldschmidt-Ieitz, Hoppe-Seyler Zs. r. physiol. Chemie, Bd. 125,150), 92 parts by weight of'sodium cbloride,'2 parts by weight of sodium' salt of .trimethylamine- :':"-tricarboxylic acid and .8- part by weight of primary sodium phosphate.

  • 92 parts by weight of'sodium cbloride 92 parts by weight of'sodium cbloride
  • a desizing gent which retains its activity metal salts consists 014.5 parts of dry amylase preparation made from Bacillus mesentericus,
  • a desizing agent is made by mixing 4 parts of dry pig pancreas, ,2 parts of calcium iormate, 86 parts of sodium chloride, 5 parts of anhydrous sodium sulphate and 3 parts of potassium salt of acid.
  • a desizing agent consists of 6 parts of dry pig pancreas, 2 parts of primary sodium phosphate, 90 parts or sodium chloride and'4 parts of sodium iminodiacetate.
  • sodium imino-diacetate there may be used, for example, an alkali salt of the N-methyl- -or N-ethyliminodiacetic acid or of the N-(ortho-carboxyphenyl) imino-diacetic acid or of the C,C'-dimethyl-trimethylamine-e:'2m"- tricarboxylic acid and the like compounds.
  • alkali salts other watersoluble salts may be used, for example ammonium salts or salts of organic bases; also mixtures of several such substances may be used.
  • a d'esizing bath is made by dissolving 5 parts of malt amylase and .5 part of ethylenediaminetet'racetic acid in 1000 parts of water at about '50v C.
  • the pH-value is adjusted to about 5.
  • the enzyme preparations used may 35.
  • a desizing agent which comprises amylase and'a water-soluble compound of the formula:
  • R1 to Rs stand for hydrogen, an aliphatic, 'cycloaliphatic or aromatic residue and K for a cation which does not disturb the action of the amylase.
  • Adesizing agent comprising amylase and a water soluble alkali metal salt of trimethyl trimethylaminea a '-tricarb oxylic I comprises amylase
