Title: Synthetic crystalline zeolites
IPC: C01B39/02
Filed: 1958-09-17
Abstract: A synthetic zeolitic aluminosilicate molecular sieve, designated zeolite M of formula <FORM:0896783/III/1> having a characteristic X-ray diffraction pattern, wherein M is a metal ion of Groups I and II of the Periodic Table, hydrogen or ammonium and y is the valency of M, is prepared by first forming a potassium aluminosilicate of the above formula and forming the other isomorphs by ion exchange of the potassium form.  The potassium form may be prepared by reacting aqueous potassium aluminosilicate mixture of composition which may be expressed as: K2O/SiO2 from 7 to 10, SiO2/Al2O3 from 7 to 10, and H2O/K2O from 5 to 7 and maintaining the mixture at 100 DEG  to 120 DEG C. until the desired zeolite forms. The zeolite crystals are separated from the mother liquor and washed with water until the pH is from 9 to 12.  According to an example, the potassium form was prepared by reacting potassium hydroxide and aluminium hydroxide and the solution was then added at room temperature to potassium silicate solution and the mixture stirred.  Crystallization was effected by heating to 100 DEG C. for about 66 hours and a product of formula 1,08K2O : Al2O3 : 2,13SiO2 : 1,7H2O was separated.  Such zeolite may be activated at temperatures of about 300 DEG C., if desired under reduced pressure, and may be employed as an adsorbent which shows selectively towards polar molecules and high adsorption capacity at low pressures and concentrations. Reference is made to its utility for adsorbing water and methanol. The ion exchanged isomorphs may be prepared by treatment with an acid such as hydrochloric acid for hydrogen exchange, silver nitrate for silver or the chlorides of ammonium and calcium for exchange of these cations.

Patent GB-638356-A (GB)
Title: Improvements in regenerated protein fibres and process for preparation thereof
IPC: D01F4/00
Filed: 1946-10-07
Abstract: A protein solution is extruded into a coagulating bath and the filaments obtained are stretched and then, while still in a freshly coagulated condition, are treated with two or more substances which condense with each other to form an insoluble condensation product in the protein of the fibre, the condensation being allowed to take place in the presence of free acid at a pH below the isoelectric range of the protein.  If desired, the filaments may be treated with a water-soluble pre-condensate of the condensable substances.  The filaments may be impregnated with one of the components and then with the other component of the condensation product, or one may be dissolved in the spinning solution, and the formed filaments may be treated with the other component.  The isoelectric region of many proteins lies between pH 3.5 and pH 5.5.  The treatment imparts increased strength and toughness to the filaments, and it also gives increased resistance to elongation, resistance to the action of scouring, dyeing or laundering liquors; improved resilient handle; and a whiter, delustred and wool-like appearance.  The condensation product may be derived from a mono- or poly-functional compound, e.g. from aldehydes, ketones, amides, amines, sulphonic acids, carboxylic acids, thiocyanates, hydroxy compounds, amino acids and phenolic compounds.  It may be formed from formaldehyde and urea, melamine, benzamide, caproamide, phenol, ammonium thiocyanate, sucrose or polyethylene glycol, or from any of these mixtures together with methanol.  In an example, an alkaline solution of peanut protein is spun into an acidified sodium sulphate bath, and the filaments produced are stretched and wound on a reel.  The filaments are treated as they are being wound with an acidified solution of sodium chloride.  The filaments are cut to staple fibre while still wet and are then impregnated for several hours with an acidified salt solution containing formaldehyde and urea. In other examples, the hardening bath is an acidified salt solution containing formaldehyde and melamine or phenol, or a water dispersible melamine-formaldehyde condensate.  In other examples, the freshly produced filaments are treated with an acidified salt solution containing urea and are then allowed to collect in a bath containing an acidified salt solution and formaldehyde.  In other examples, fibres obtained from milk casein and soya bean protein are treated.  The filaments may be cut to staple fibre between the treatment with urea and the treatment with formaldehyde.  Specification 559,818 is referred to.
