The present invention composition features pharmaceutically acceptable salts of psilocin and compositions thereof. The pharmaceutically acceptable salts of psilocin may be used to treat a disease or condition, such as a neurological injury, an inflammatory condition, chronic pain, or a psychological condition, in a subject in need thereof.

Electrodeionization apparatuses, systems including a reactor system and an electrodeionization system, and methods of purifying acetic acid are provided herein. In some embodiments, the electrodeionization apparatus includes an anode, and three spaced apart membranes located between the anode and the cathode: a first cation exchange membrane, a first anion exchange membrane, a second cation exchange membrane, defining: a first electrode rinse passage between the anode and the first cation exchange membrane, a first concentrate passage between the first cation exchange membrane and the first anion exchange membrane, a feed stream passage located between the first anion exchange membrane and the second cation exchange membrane, and a second electrode rinse passage between the second cation exchange membrane and the cathode. In some embodiments, the electrodeionization apparatus also includes at least one propionate-selective ion exchange resin wafer within the feed stream passage.

The invention relates to a process of the oxidative dehydrogenation of an alkane containing 2 to 6 carbon atoms and/or the oxidation of an alkene containing 2 to 6 carbon atoms, wherein oxygen, water and the alkane and/or alkene are fed to a reactor and are contacted with a mixed metal oxide catalyst containing molybdenum, vanadium, niobium and optionally tellurium in the reactor, and wherein the molar ratio of water as fed to the reactor to oxygen as fed to the reactor is smaller than 1:1.

A quaternary ammonium compound represented by the following formula (1):

[(R1).sub.m(R2).sub.4-mN.sup.+].sub.nX.sup.n(1)

wherein each R1 independently represents an unsubstituted alkyl group or substituted alkyl group having 1 to 30 carbon atoms; an aryl group having 6 to 20 carbon atoms; an aralkyl group where an unsubstituted alkyl group or substituted alkyl group having 1 to 30 carbon atoms is substituted with at least one aryl group having 6 to 20 carbon atoms; or an alkylaryl group where an aryl group having 6 to 20 carbon atoms is substituted with at least one unsubstituted alkyl group or substituted alkyl group having 1 to 30 carbon atoms;

each R2 independently represents a group having 2 to 60 carbon atoms and 2 to 30 oxygen atoms, the group represented by the following formula:

(RO)k-H, wherein R represents a substituted or unsubstituted alkyl group and k represents a natural number of 2 or more.

The invention relates to a method for the production of calcium dipropionate by a batch process in a single pressure-resistant reaction vessel. The reaction vessel is charged with calcium oxide, calcium hydroxide, calcium carbonate or a mixture thereof. Then, pure high-concentrated propionic acid, preferably in a concentration of above 99% is added to the solid raw materials. The heat (up to 160 C.) and pressure (up to 10 bar) are retained in the reaction vessel and are subsequently used to discharge the reaction water after the complete amount of acid has been added. After a reaction time of 3 to 6 hours, pure calcium dipropionate with a water content of below 1% is obtained.
