The American Chemistry Council estimated that global chemical sales in 2014 rose by 3.7% to US$5,389,000,000,000. [3] In 2018, Forty-eight of the companies on the list disclosed chemical profits, which totaled US$110,100,000,000, an increase of 1.3% from 2017. The average profit margin for chemical operations for these companies was 9.6%. [1]
The living nature of NMP is due to the persistent radical effect (PRE). [3] The PRE is a phenomenon observable in some radical systems which leads to the highly favored formation of one product to the near exclusion of other radical couplings due to one of the radical species being particularly stable, existing in greater and greater concentrations as the reaction progresses while the other ...
Commodity chemicals are a sub-sector of the chemical industry (other sub sectors are fine chemicals, specialty chemicals, inorganic chemicals, petrochemicals, pharmaceuticals, renewable energy (e.g. biofuels) and materials (e.g. biopolymers)).
