| titleOfInvention | A PROCEDURE FOR THE OBTAINING OF CHLOROPHYLL |
| abstract | A process for obtaining chlorophyll, characterized in that the flour resulting from the drying and grinding of chlorophyll plants, is deposited in a tank with a perforated bottom provided with a filter and agitator, the whole of which is coated with copper to avoid contact with the iron. The solution, where for a period of time that will range between 30 and 60 minutes, is perfectly interposed with cold ethyl alcohol of high concentration contributed in proportion of three to four parts for one of flour, also adding 1% copper sulfate in concentrated aqueous solution; this mass is then pressurized in the tank so that the solution passes filtered through the perforated bottom, going to a second analogous extractor containing a new charge of dry flour, with which it will also be interposed by means of agitation. When another thirty or sixty minutes pass, the alcoholic solution is also extracted by means of pressure, which is increasingly rich in chlorofluorine at the saturation acquired as it passes through the battery of extractors, and a copper caldera heated outside by means of steam is carried., in order to distill the solvent in order to isolate the residue that forms an oily mass, while the separated alcohol is fit, to start a new extraction cycle.
