Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1907 edition. Excerpt: ...tetrachloride has been looked upon as a possible relief in this direction. It has to its advantage over benzine and naphtha (the most common solvent at present) its ability to extract the desired product more proficiently, both in purity and brevity of time. It is a clear, colorless liquid (sp. gr. 1.604) with an agreeable aromatic odor, free from inflammability and explosivencss, and it is known that its vapors extinguish flame. (Boiling point 780 C.) This feature is one that would meet with favor, especially where the State and Municipal laws governing lire risks by the use of benzine and naphtha are items of moment in the installation of an extracting plant.

As an extracting medium it shows remarkable ability in its action on fats, oils from oil seed, oil cake, animal tankage, wool, cotton and other fat-bearing materials. Up to the present time there is, so far as the author knows, no system where its efficiency on an economical scale has been worked out on a commercial basis to prove its advantages over benzine and naphtha. What practical knowledge has been secured up to the present time has given it due credit for its great solvent powers, but its excessive cost has hindered it being taken up seriously by the manufacturers. Therefore, a few points will have to be settled definitely, and to the satisfaction of the would-be consumer, before he is convinced of its adaptability over the present solvents now used.
