Abstract

A procedure for obtaining an optical brightener, which in a specific case consists of dissolving in distilled water a four hundred per thousand hexanopentolal at room temperature and raising the temperature of the solution to exceed 36 degrees centigrade without exceeding fifty ; On the other hand, at a temperature of between 170 and 175 degrees centigrade, a three hundred per thousand KHC4H4O6 is added, which is diluted in distilled water at the same temperature. When the two previous solutions are prepared, they are mixed in a tank whose walls are completely unattackable by acids, bases or other substance with which naturally-the temperature will balance around 70 to 80 degrees centigrade .- In separate tanks and ordinary temperatures are prepared aqueous solutions carefully distilled water carbonates and bicarbonates of alkaline and alkaline earth metals: For To cite a specific case we will refer to the one in which one hundred per thousand of lithium carbonate and one hundred per thousand of sodium carbonate (naturally bicarbonated) are used. Apart from and starting from insoluble organic substances of at least three carbon atoms and also containing NH2 groups; NH; O = N-, in the molecule, the substance thus synthetically obtained is mixed in one per thousand to the aforementioned alkaline solutions and the whole is dissolved in the aforementioned solution which has been maintained at a temperature of 70 to 80 degrees centigrade; the whole is mixed with agitation of all its components and dried by extraction of the water by vacuum vaporizers, thus obtaining a powder to which slightly colored or slightly perfumed substances are mixed for commercial purposes only and for which use it could therefore be used. dispense (Machine-translation by Google Translate, not legally binding)
