Improvements in Disinfectants ancl Antiseptics, and in Disinfectant and Antiseptic Soaps. I Mark Hargreaves of Fylde Road, Preston, in the County of Lancaster, Chemist, do hereby declare the nature of this invention to be as follows :— My invention consists in forming chlorophenol acids by combining carbolic or cresylic acids, vegetable tar, or the like (hereinafter referred to as phenols) with chlorine in suitable proportions, and at suitable temperatures, and forming readily decomposable chlorophenol salts by combining the said chlorophenol acids with alkali or alkaline earth. The said chlorophenol acids may be formed by blowing chlorine gas through the said phenols or by passing the said phenols down a suitable tower in which a current of chlorine gas ascends, or by other suitable means chlorine gas is caused to pass through or amongst the said phenols. 1 directly form the said chlorophenol salts by adding hypochlorites or equivalent salts of the alkalies or alkaline earths in presence of water to the said phenols, or I pass chlorine gas through or amongst, or I mix hypochlorites writh the said phenols when combined or mixed with alkali or alkaline earth in the presence of water. To obtain the said chlorophenol acids or salts for use as disinfectants in the form of powder 1 mix the said acids or their salts (preferably in solution) with suitable powdery absorbents such as lime or its carbonate, sand, sawdust or like materials. Carbonate of lime (preferably after being thoroughly dried by heat) resulting as a bye product in the manufacture of caustic soda is suitable for use as an absorbent. When a disinfectant or antiseptic soap is desired 1 mix the hereinbefore described chloroplenic acid or its salts with any ordinary soap. Dated this Eighteenth day of November 1889. Per pro. J. T. KING, W. B. Johnson, Agent. COMPLETE SPECIFICATION. Improvements in Disinfectants and Antiseptics, and in Disinfectant and Antiseptic Soaps. I Mark Hargreaves of 7 Fylde Road Preston in the County of Lancaster, Chemist do hereby declare the nature of this invention and in what manner tho same is to be performed, to be particularly described and ascertained in and by the following statement:— First. My invention consists in forming chlorophenol acids and like chloro com¬ pounds suitable for use as disinfectants and antiseptics by combining carbolic or cresylic acids, vegetable tar, or the like (hereinafter referred to as phenols) with chlorine in suitable proportions, and at suitable temperatures and forming readily decomposable chlorophenol salts by combining tho said chlorophenol acids with alkali or alkaline earth. The said chlorophenol acids may be formed by blowing chlorine gas through the said phenols or by passing the said phenols down a suitable tower in which a current of chlorine gas ascends, or by other suitable means chlorine gas is caused to pass through or amongst the said phenols. I combine about three parts by weight of chlorine with about two parts of phenols. During combination much heat is evolved ; I keep the temperature of the phenols below boiling point and preferably between 100° [Price 4(A]
