Title: Preparation of resinous condensation products
IPC: C08G12/18
Filed: 1943-08-18
Abstract: A resinous condensation product useful as a textile assitant, paper or leather softener, adhesive, wetting agent, emulsifying or deemulsifying agent, anticeptic agent, insecticide, flotation agent, or as a moulding composition or in photographic developers, is prepared by heating cyanamide or guanidine with dextrose, sucrose or starch and a member of the group consisting of casein, fatty acids and primary aliphatic amines containing six or more carbon atoms. The cyanamide or guanidine and the dextrose, sucrose or starch may first be heated together, e.g. at 80-180 DEG  C. and the product then heated with the remaining ingredient.  In example 1 dextrose, cyanamide and water are heated together on a steam bath, the product mixed with dodecylamine hydrochloride and gradually heated to 110 DEG C.  The product was dispersible in water, with water-softening and textile-softening properties.  Example 2 was similar but used the mixed hydrochlorides of octa- and decylamines.  In example 3 a mixture of 90 per cent lauric and 9 per cent myristic acid was heated with dextrose and cyanamide to 90 DEG  C. whereon an exothermic reaction raises the temperature to 110 DEG  C.  In example 4 a mixture of 90 per cent palmitic, 6 per cent stearic and 4 per cent oleic acid was heated with dextrose and cyanamide to 105 DEG  C., which the reaction raises to 110 DEG  C.  In example 5 sucrose and cyanamide were heated to 140 DEG  C. which the heat of reaction increased to 160 DEG  C. 3-octadecoxypropylamine, water and acetic acid were mixed with the heated product.  In Example 6 sucrose and cyanamide were heated, the temperature rising to 170 DEG  C., the product heated with casein until no more dissolves and then the excess casein dissolved in more sucrose-cyamide condensation product. In example 7 starch, tapioca flour and cyanamide were heated with aqueous hydrochloride acid, and the product heated with acetic acid and a mixture of hexaocta- and decylamines.  In example 8 guanidine carbonate, water, hydrochloric acid, and tapioca flour were heated under reflux, neutralised, filtered and evaporated nearly to dryness. The product was heated with acetic acid and 3-octadecoxypropylamine. A mixture or solution of the resin ingredients may be applied to cloth or other material and the resin forming reaction carried out on the material.ALSO:A synthetic resin obtained by heating and stirring a mixture of dextrose and cyanamide on a steam bath, and reacting the product at 110 DEG C. with dodecylamine hydrochloride has excellent water-softening properties.

Title: Method and apparatus for handling dispersions, such as spinning solutions, which undergo change on keeping
IPC: D01D1/06
Filed: 1942-10-01
Abstract: 553,490. Apparatus for handling dispersions such as spinning solutions. AMERICAN VISCOSE CORPORATION. Oct. 1, 1942, No. 13770. Convention date, Oct. 4, 1941. [Class 2 (ii)] [Also in Group XVII] In withdrawing from a series of supply tanks dispersions which undergo change on keeping, e.g. viscose or other spinning solutions the residue normally left in each tank with the object of avoiding the entraining of air in the liquid is reduced in volume by withdrawing it at a controlled, relatively slow rate and discharging it into a stream of the dispersion being withdrawn from a second supply tank. In the example illustrated tanks 1-6 are emptied in series through taps 15-20 under suction from a pump 22 and if desired under pressure from a pressure air line 7a. The last portions of the contents of any one tank are withdrawn slowly through one of the cocks 26-31, while the next tank is emptying at its normal rate. The residue left in each tank is thus reduced to a minimum. Alternative connections are described.
