Usage

General Description

4,4'-Isopropylidenediphenoxyacetic acid is a synthetic chemical compound belonging to the class of compounds known as diarylethers. Likely used in industrial processes, it is formed through the combination of phenol, isopropyl alcohol and acetic acid. It has two phenol rings, joined by an isopropyl bridge, and a carboxylic acid group. This complex structure may give it potential as a ligand in coordination chemistry, and its physical and chemical properties, as well as potential uses or effects, would be largely determined by its specific structure. However, specific information on its use, toxicity or potential applications is not readily available.

Organic precipitator as well as preparation method and application thereof

The invention belongs to the field of rare earth gathering, and particularly relates to an organic precipitator as well as a preparation method and application thereof. The organic precipitator provided by the invention is prepared from one or more of structural compounds of formula (I) to formula (III), wherein R1, R2, R3 and R'3 are independently selected from hydrogen, substituted or non-substituted linear chain alkyl with the number of carbon atoms of 1 to 10, substituted or non-substituted branched alkyl with the number of the carbon atoms of 3 to 10, and substituted or non-substituted aryl; n is a natural integer; and M indicates cations. The organic precipitator provided by the invention has good selectivity to the rare earth and is very suitable for gathering rare-earth elements in a low-concentration rare-earth solution. The experiment result shows that when the organic precipitator provided by the invention is used for gathering the rare earth in the low-concentration rare earth solution, the precipitation speed is high, the purity of the gathered rare earth product is greater than 96 percent, and the yield is greater than 95 percent. (The formula (I) to (III) are shown in the description).

Tryptase inhibitors

The invention relates to novel inhibitors of human tryptase which are used in the pharmaceutical industry for the production of medicaments.
