Book Description
Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 13: 1920-21 With reference to the first possibility, competition based on cut throat slashing of prices always has proved disastrous to the whole industry. Moreover, the mining of sulphur by the Frasch-process, to be carried out economically, must be conducted on a very large scale, SO that even if a company under the conditions outlined above had Obtained a third of a possible - ton consumption, this would not have insured profitable Operation. The company has chosen what is surely the wiser course, in attempting to place its sulphur by increasing the total consumption in the industries. It was possible to do this owing to the prevailing economic conditions. The United States had in recent years consumed an r.-1ally, for the manufacture of sulphuric acid, upward of tons Of sulphur in the form of pyrites, most of which came from Spain. The Older sulphur companies, either because of some agreement with the pyrites importers or because Of a desire to hold the price of sulphur at a certain level, had not attempted seriously in past years to substitute sulphur for pyrites as the raw material of sulphuric acid manufacture. Importation of Spanish pyrites, due to war transportation conditions, fell Off very seriously during the war years. This caused many producers of sulphuric acid to discard the pyrites roasters and to install sulphur-burning equipment, while new producers in this field erected plants which were almost entirely so equipped. The new company was able to Obtain its fair propor tion of the new business and the net result has been that the total consumption of sulphur Of the United States during the past year has been upward of tons, as compared with a normal consumption in recent years of about half that figure.

Book Description
Excerpt from Transactions of the American Institute of Chemical Engineers, 1912, Vol. 5 If we first produce the pure crystalline phenol-alcohol, contain ing no excess Of phenol, for instance crystalline saligenin or oxybenzyl-alcohol, and if we heat it gently, it will simply dehydrate and be transformed in a fusible mass which on cooling, solidifies to a resinous product - a fusible saliretin resin. The latter, submitted to the further action of heat, polymerizes and becomes an infusible, insoluble saliretin. This polymerization is facilitated, by the pres ence of small amounts of catalyzers, for instance, hydrochloric acid. The presence of an excess of phenol retards polymerization; hence the infusibility induced by polymerization will be retarded, and this, until some way or another the excess Of phenol has been expelled. The infusible polymerized saliretin obtained by heating phenol-alcohols containing no free phenol, or by heating fusible saliretin containing no free phenol, is insoluble in alcohol, but swells in acetone; it softens decidedly on heating, although it is no longer fusible. Longer heating does not harden it further, nor make it more resistive. It is harder, stronger, and more resistant to physical and chemical agents than the fusible saliretin from which it is derived; in this respect, it surpasses even more the soluble fusible resins described by Blumer, delaire, Baekeland, and called phenol resin by Aylesworth. But even after polymerization or hardening has been carried as far as possible, it is considerably less hard and less strong and less resistant to physical and chemical agents than the polymerization products resulting from the reaction of phenol on a sufficiently large proportion of formaldehyde or equivalent substances. In order to obtain the latter polymerization products of maxi mum strength. Hardness, and maximum resistivity, an adequately larger amount of methylen group must be introduced before or dur ing the act of polymerization. The introduction of this methylen group may be accomplished by at least three distinct methods. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Transactions of the American Institute of Chemical Engineers, Vol. 14: 1921-22 Sulphuric acid is universally concentrated by the application of heat. The first interest of the designer of apparatus to concentrate sulphuric acid must hence lie in the thermal properties of sulphuric acid. Several articles have been written on this subject, and one of them at least has treated the subject very thoroughly and comprehensively. The results, however, are not most conveniently expressed, and the original article is not particularly accessible. This, then, must be the excuse for the present attempt to present an old subject from a different viewpoint. The first thermal property of sulphuric acid which interests us is its specific heat.
