Optimization of O-sulfonated phenol production for cumene hydroperoxide cleavage
A method for the manufacture of a sulfonated phenol for use as a cumene hydroperoxide decomposition catalyst can comprise: combining phenol and a sulfonating agent at a first temperature that is 1 C. to 15 C. higher than a melting temperature of the phenol, to form a reaction mixture at the first temperature; reducing the first temperature of the reaction mixture to a second temperature that is 10 to 40 C. lower than the first temperature; and forming the sulfonated phenol at the second temperature.

High Solubility Thioether Quinones
Substituted hydroquinones and quinones and methods of synthesizing such compounds are disclosed herein. The substituted hydroquinones have the formula:
##STR00001##
while the substituted quinones have the corresponding oxidized structure (1,4-benzoquinones). One, two, three, or all four of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 comprise a thioether moiety and a sulfonate moiety, and wherein each R.sup.1, R.sup.2, R.sup.3 and R.sup.4 that does not comprise a thioether and a sulfonate moiety sulfonate moiety is independently a hydrogen, an alkyl or an electron withdrawing group.
The substituted hydroquinones and quinones are soluble in water, stable in aqueous acid solutions, and have a high reduction potential in the oxidized form. Accordingly, they can be used as redox mediators in emerging technologies, such as in mediated fuel cells or organic-mediator flow batteries.

Cannabidiol-3-sulfonic acid, preparation method and application thereof, and cannabidiol derivative
The present invention relates to a cannabidiol-3-sulfonic acid, a preparation method and application thereof, and a cannabidiol derivative. The present invention introduces a sulfonic acid group in a molecular structure of cannabidiol, and the sulfonic acid group as a polar group can increase the polarity of cannabidiol, thereby improving the water solubility thereof. The cannabidiol-3-sulfonic acid can be subjected to a salt forming reaction with an inorganic base or an organic base, so that the water solubility of the cannabidiol is further improved, and the druggability of a drug based on a parent nucleus and physiological activity of the CBD structure can be enhanced. The newly introduced sulfonic acid group in the cannabidiol-3-sulfonic acid provided by the present invention can be used as a new action site to react with a specific group, and the research and application range of the cannabidiol-3-sulfonic acid is further broadened.
