Improvements in Disinfectants and Deodorizers. I, Joseph Price, of 58 Lombard Street, in the City of London Accountant, do hereby declare the nature of this invention to he as follows :— The main object of my invention is the preparation of a compound or admixture of certain chemical substances for disinfecting, deodorizing, and purifying infectious, 5 offensive and noxious gases and foul or decaying vegetable or animal matters, such compound being not only efficacious and portable but more useful and economical than any preparation for similar purposes in ordinary use. It is well known that oxygen and chlorine are the most powerful disinfectants yet discovered, and that their combination with any substance in a portable or convenient 10 state for dealing with offensive effluvia, or decomposing and putrescent matters is an object worthy of attainment, as such a compound would do double duty by readily attacking impurities contaminating the atmosphere or escaping from aqueous bodies, as well as arresting the decomposition of, and purifying the offensive animal and vegetable matters therein contained. 1 The methods which have been proposed for accomplishing these desiderata have always had some disadvantage, the materials employed to hold the two gases, oxygen and chlorine, in combination, were either too expensive or unsuitable for commercial purposes. The materials I prefer to employ are manganate of soda and chloride of lime, but 20 1 may use other compounds containing oxygen and chloride, and I mix or blend these with a, comparatively speaking, waste chemical product, known as “ Salt (Jake ” (sulphate of soda) the residuum from the chemicals used in the manufacture of muriatic, nitrous, or nitric acids, which is in itself a highly antiseptic salt. This combination has many advantages over other disinfectants, which usually 25 contain only one of the two principal elements in question, and are often mixed with lime, chalk, terra alba, sawdust, or other indissoluble matters, which choke up the drains and sewers. 1 prepare my compound in a perfectly free and dry state, in which condition it may be used and when exposed in shallow or other vessels it emits chlorine in a steady continuous and effective manner for a week or ten days, without 30 appreciably deliquescing, destroying all noxious and offensive smells within a wide radius, and it is, after the exposure, almost as efficacious (having acquired additional oxygen whilst emitting the chlorine) for treating foul water and putting down sinks, drains, water closets &c., as when used direct for such purposes. Another very important feature in my preparation consists in its solubility in 35 water and it therefore will not choke up or clog the drain pipes, or sewers, and consequently it is especially adapted for household purposes, barracks, hospitals, workhouses, stables, or other buildings draining into the common sewers, where it would finish its work by destroying the foul gases and purifying the fluid matters. 40 From experience, I find that the most suitable proportions of the ingredients which I combine for the purposes enumerated, having all ends in view, are as follows :— 1 part manganate of soda, 1^ parts chloride of lime, 45 17^ „ salt cake (sulphate of soda), but I may vary or determine the proportions under special circumstances and conditions, whicn might present themselves in practice. As the salt cake contains a small portion of free hydrchloric or nitric acid, it is a [ Price 6cJ.]
