Nootkatone is a naturally occurring sesquiterpenoid with a grapefruit-like odor and slightly bitter in taste. It was first isolated from the heartwood of Cupressus nootkatensis (Alaska cedar) (Leonhardt and Berger 2015). Minute amount of it can be found in grapefruit and pummel.

Triacetin, is the organic compound with the formula C3H5(OCOCH3)3. It is classified as a triglyceride, i.e., the triester of glycerol. It is a colorless, viscous, and odorless liquid with a high boiling point and a low melting point.

Isonicotinic acid is a pyridinemonocarboxylic acid in which the carboxy group is at position 4 of the pyridine ring. It has a role as a human metabolite and an algal metabolite. It is a conjugate acid of an isonicotinate.

Barium hydroxide has the molecular formula of Ba(OH)2 and the molecular weight of 121.6324 g/mol. It occurs as an anhydrate whose prismatic, colorless crystals are very deliquescent. Barium hydroxide can be prepared by dissolving barium oxide

Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH3CH2SH. is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH3CH2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in

Didecyldimethylammonium chloride (DDAC) is a quaternary ammonium compound used as antiseptic/disinfectant. It causes the disruption of intermolecular interactions and the dissociation of lipid bilayers.

Octanol appears as a clear colorless liquid with a penetrating aromatic odor. Insoluble in water and floats on water. Vapors heavier than air. Vapors may irritate the eyes, nose, and respiratory system.

Polysulfone, any of a class of resinous organic chemical compounds belonging to the family of polymers in which the main structural chain most commonly consists of benzene rings linked together by sulfonyl (―SO2―), ether (―O―), and isopropylidene (―C(CH3)2―) groups.

Is a catalyst in transesterification of specific oils and fats. Almost all oils and fats can be transesterified using potassium catalysts (e.g. for biodiesel production).

Is an amorphous material obtained from the sulfite pulping of softwood. The lignin framework is a sulfonated random polymer of three aromatic alcohols: coniferyl alcohol, p-coumaryl alcohol, and sinapyl alcohol, of which coniferyl alcohol is the principle unit.
