The present disclosure provides a system for refining long chain dicarboxylic acid, comprising: a first membrane filtration unit, for a first membrane filtration of a long chain dicarboxylic acid fermentation broth or a treated liquid therefrom; a first decolorization unit, for carrying out a first decolorization treatment to the filtrate obtained after the membrane filtration; a first acidification/crystallization unit, for carrying out a first acidification/crystallization of a filtrate obtained after the membrane filtration to give a solid-liquid mixture; a first separation unit, for a solid-liquid separation of the solid-liquid mixture; a drying unit, for drying the solid separated by the separation unit to give a first solid. By using the refining system according to the present disclosure, the purity of the obtained product is high, and the disadvantages such as poor quality of the product obtained by crystallization from a solvent and environment pollution caused by a solvent can be overcome.

A process of converting cannabidiol (CBD) to Δ.sup.8-tetrahydrocannabinol (Δ.sup.8-THC) or Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) can enable mass production of Δ.sup.8-THC and/or Δ.sup.9-THC, achieve greater yields and higher purity in comparison to previously reported processes while eliminating the use of organic solvent. The resultant hemp-derived Δ.sup.8-THC can be mixed with and absorbed by natural extracts, including tea extract, starch, sugar, lecithin, and other emulsifiers. Δ.sup.8-THC used in edible, topical and vaping products such as powdered Δ.sup.8-THC food ingredients, tablets or pills, suppositories, and vape formulations are disclosed. Further described are beverages and baked goods utilizing or incorporating the tablets or powdered Δ.sup.8-THC to create edible products containing an emulsified, tasteless, and odorless dose of Δ.sup.8-THC. The disclosure also describes a rectal suppository designed to provide improved comfort of use. A Δ.sup.8-THC liquid composition can be use in an electronic cigarette smoking device for pulmonary administration of Δ.sup.8-THC, which results in more effective absorption.
