Title: Improvements in the preparation of chromates and dichromates
Filed: 1933-04-27
Abstract: In the manufacture of chromates or dichromates by oxidizing chromium or its alloys in an aqueous medium at temperatures above 100 DEG  C. under pressure, any other substances capable of yielding alkali or alkaline-earth during the reaction are used in place of or together with the alkali or alkaline-earth hydroxides, carbonates, or bicarbonates employed according to the parent Specification.  In the manufacture of dichromates the alkali &c. yielding substance may also replace the monochromate used in the parent Specification.  The alkali &c. yielding substance may act also as oxidizing agent for the reaction, and mixtures of substances which yield alkali only and which both yield alkali and act as oxidizing agents may be employed. Specified substances which may be used are alkali or alkaline-earth sulphates, chlorides, phosphates, acetates, silicates, aluminates, nitrates, chlorates, persalts, manganates, and permanganates.  In one example a mixture of ferrochrome, anhydrous sodium sulphate, calcium carbonate, and water is heated at 280-290 DEG  C. in a current of air or oxygen under pressure to obtain sodium dichromate; by using more sodium sulphate sodium monochromate is formed.  In another example, potassium dichromate is obtained from ferrochrome by the action of potassium chlorate in the presence of calcium carbonate at 290-300 DEG  C. oxygen under pressure being passed through only towards the end of the reaction.  In a further example using trisodium phosphate and a reaction temperature of 280-300 DEG  C. in a current of air or oxygen, sodium monochromate and disodium phosphate are formed.  In a last example, potassium dichromate is obtained from ferrochrome and potassium sulphate, an alkaline-earth oxide or carbonate being preferably present to neutralize the free sulphuric acid formed.

Abstract: 280,605. Bartmann, L. May 18, 1926. Hulling, husking, and decorticating; electric treatment; agitating; reduction processes; treatment by cooling, damping, and heating; treating with air and gases.-To paralyse or to kill the embryos or germs of cereals subjected to steeping in a medium such as water for the purpose of causing the endosperm to swell, formaldehyde or a dilute aqueous solution thereof is added, or rapid changes are made in the temperature of the grains, or they are subjected to mechanical or electrical shocks. The duration of the steeping process depends upon the cereals treated, a non- husked rye requiring about 16 hours and non- husked wheat 20-25 hours. The swelling may be interrupted at any point and the process reversed by cooling or by drying at 30-35‹ C. or by adding chemicals such as salt. The formaldehyde may be added in a 30-40 per cent. aqueous solution until the steeping water contains 0.2 per cent formaldehyde, the grains being treated for a few seconds in the solution and then for a longer time with 0.1 per cent solution and later with a still weaker solution, pure water finally being used. Antiseptically acting or paralysing chemicals may be used with the formaldehyde. The steeping operation may be carried through in several different liquors, the grains for example being first placed in a weak acid, then in a weak alkali, and finally in a liquor containing formaldehyde, The grains may be dipped for a few seconds into boiling water and then quickly into cold water or into a refrigerating solution, the steeping proper then being proceeded with at a temperature of about 30-35‹ C. Substances hitherto used for improving the baking capacity of the flour, such as ammonia, may be added during the steeping. The steeping may be done in flowing water. After the steeping is completed the grains may be slightly dried, and subjected to pressure to expel the endosperm. If it is not desired to separate the softened endosperm the grains can be crushed or cut in disintegrating mills or the like and a wholemeal bread directly produced therefrom by a fermentation and baking process.
