Nitric acid commercial demand

Suberic Acid. This acid is not produced commercially at this time. However, small quantities of high purity (98%) can be obtained from chemical supply houses. If a demand developed for suberic acid, the most economical method for its preparation would probably be based on one analogous to that developed for adipic and dodecanedioic acids air oxidation of cyclooctane to a mixture of cyclooctanone and cyclooctanol. This mixture is then further oxidized with nitric acid to give suberic acid (37). [Pg.62]

This concentration process has been operated on a commercial scale for some fifteen years and has proved robust and reliable. Weak nitric acid feedstocks with concentrations varying from 55 to 70 wt% HNO3 have been handled satisfactorily with product strengths of 98-99.6 wt% HNO3 according to demand. [Pg.147]

Commercial lead arsenate usually consists mainly of the monohydrogen arsenate, but may also contain the normal arsenate. It is in great demand as an insecticide (see p. 301). Many methods of manufacture are described in the patent literature,14 some of the more recent being as follows (1) Metallic lead and arsenious oxide are added to a concentrated solution of arsenic acid containing nitric acid 15 lead arsenate is precipitated, the concentration of the arsenic acid remaining constant. At intervals the precipitate is removed and the arsenic acid solution again treated. (2) A solution of a soluble arsenate is treated... [Pg.206]

The demand for nitrogen in a chemically fixed form (as opposed to elemental nitrogen gas) drives a huge international industry that encompasses the production of seven key chemical nitrogen products ammonia, urea, nitric acid, ammonium nitrate, nitrogen solutions, ammonium sulfate and ammonium phosphates. Such nitrogen products had a total worldwide annual commercial value of about US 50 billion in 1996. The cornerstone of this industry is ammonia. Virtually all ammonia is produced in anhydrous form via the Haber process (as described in Chapter 2). Anhydrous ammonia is the basic raw material in a host of applications and in the manufacture of fertilizers, livestock feeds, commercial and military explosives, polymer intermediates, and miscellaneous chemicals35. [Pg.15]

Oxidation catalysts were among the first to be described and then developed industrially. Because of the energy evolved, oxidation processes were originally known as catalytically induced combustion. Some of the earliest catalytic oxidation reactions used commercially are shown in Table 4.1. This list could also include the Deacon and the Claus processes, which were described in Chapter 2. Subsequently, nitric acid and formaldehyde were produced on a large scale by catalytic oxidation processes. In most early processes, once a reasonable eatalyst had been developed, production was limited only by demand and the availability of efficient equipment. [Pg.119]
