An expanded porphyrin-biscopper hexaphyrin was introduced as a bioinspired molecular tweezer to co-catalyze functionalization of C(sp3)-H bonds. Theoretical and experimental investigations suggested that the biscopper hexaphyrin served as a molecular tweezer to mimic the enzymatic orientation/proximity effect, efficiently activating the N-hydroxyphthalimide (NHPI) via light-free proton-coupled electron transfer (PCET), at an exceptionally low catalyst loading of 10 mol ppm. The resulting N-oxyl radical (PINO) was versatile for chemoselective C-H oxidation and amination of hydrocarbons.

Paragraph 0148-0169, (2021/03/31)
The invention relates to a waste liquid treatment process and device in a TPO production process, in particular to a waste liquid treatment process and device based on oxidant cyclic utilization in the TPO production process. The method comprises the following steps: mixing the synthetic waste liquid with sulfuric acid and water, carrying out esterification reaction to obtain a material phase, further carrying out mixing reaction on the material phase and hydrogen peroxide, carrying out liquid separation to obtain a tert-butyl hydroperoxide phase, and carrying out alkali washing to obtain tert-butyl hydroperoxide; tert-butyl hydroperoxide can return to a TPO synthesis section to be used as an oxidizing agent for preparing TPO; by adopting the process, the problem of high treatment cost ofthe synthetic waste liquid in the TPO production process is solved; and through the waste liquid treatment process, the resource utilization of the synthetic waste liquid is realized, the raw materialpurchasing and process production costs of the TPO production process are greatly reduced, and the economic value is obvious.

Paragraph 0052-0053, (2021/02/05)
A process for oxidizing iso-butane with oxygen to produce t-butyl hydroperoxide and t-butyl alcohol; dehydrating at least a portion of the t-butyl alcohol to produce di-tert-butyl ether and isobutylene; epoxidizing at least a portion of the isobutylene with the t-butyl hydroperoxide to produce isobutylene oxide and t-butyl alcohol; and carbonylating at least a portion of the isobutylene oxide with carbon monoxide to produce pivalolactone.
