PROCESS OF THE MANUFACTURE OF A msrnmc'rnnm No. 929,383. Specification of Application filed March 10,

To all whom-it may concern:

Be it known thatl, ALEXANDER BRICK, a 1 subject of the King of Hungary, and resident of XX, Petraschgasse 4-6, Vienna, Austria- Hungary, have invented a certain new and useful recess of the Manufacture of a Dis infectant Consisting of Formaldehyde and Ethereal Oils.

I do hereby declare the following to be a full clear and exact description or the inventhe same.

Experience has shown that the use of formaldehyde in the form of spra is exceedingly important for disinfecting the interiors of. dwellings, restaurants, theaters, etc. The formaldehyde must, however, be employed in such shape that it neither irritates the mucous membrane, nor retains its penetraton the contrary, it should be so combined with ethereal oils as to be invigoratin For this purpose it is necessary to enipl 0y the formaldehyde in combination wit ethereal oils and with such' a solvent,- that it forms an emulsion with the ethereal oils with which it is Combined, also with Water, and that it can be sprayed with this. This object is best-obtained, by proceeding as follows:--A mixture is made of about 2 kilos. of soap solution gontaining about 40% alcohol (this can be soda or potash soap), a} kilogram rosemary oil, 2 kg. juniper oil, 5; kilo. oil of juniper berries, 200 grams essence of turpentine, i kilo. geranium oil, .5 kilos. r entinoifl kilos. oil of lemon, rams musk. To this mixture, there are ad ed,-;in the reflex cooler, under constant heat and'stirring, gradually, 5 kilos. formaldehyde. The iorinaldehyde Letters Patent. Patented July 27, a.

mixture, or paraformaldehyde can be heated in a retort, and the gasdeveloped therefrom conducted into the liquid in the-reflex eoole'r. In both cases the m'ixtu tion of the formaldeh 'k'le is kept constantly at a temperature of about 30 C. The para formaldehyde ran, however, also be put into the mixture and carried over in the form of gas by heating. In this last case, however the mixture must The heating of the mixturein the reflex cooler is continued some time after the addition of the formaldehyde, and thereby coir-1 densation products or" the formaldehyde are obtained with-tho ethereal oils, which, when highly diluted with w their components, namely, the-active formaldehyde and into ethereal oil. The essence recovered in the reflex cooler is, after cooling, mixed with three to four-times the amount of potash or soda soap made,- from sesame or other oils, which soap contains about 30% of free unsaponified oil and is combined with about 5% of alcohol.

Having thus fully set forth and described my invention, What I claim is:"
