Definition
ChEBI: A p-menthadiene with double bonds at positions 1 and 4(8).
Preparation
By alcoholic sulphuric acid treatment of pinene (Arctander, 1969).
Aroma threshold values
Aroma characteristics at 1%: sweet, fresh, piney citrus with a woody, old lemon peel nuance.
Taste threshold values
Taste characteristics at 2 to 25 ppm: woody, terpy, lemon and lime-like with a slight herbal and floral nuance.
General Description
A water-white to light amber colored liquid. Insoluble in water and less dense than water. Flash point 99°F. Used to make plastics and resins.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
Terpinolene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.
Hazard
Flammable, moderate fire risk.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Flammability and Explosibility
Notclassified
Pharmacology
Combinations of terpenes, such as terpinolene, with nonionic surfactants and stabilizers
have been patented for use as gallstone solvents. Human cholesterol calculi heated in mixtures
containing terpinolene and human bile were dissolved within 1-2 hr (Hisamitsu Pharmaceutical Co.,
Inc., 1973).
Safety Profile
Mildly toxic by ingestion. A very dangerous fire hazard when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. Can react with oxidning materials. When heated to decomposition it emits acrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 586-62-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 586-62:
(5*5)+(4*8)+(3*6)+(2*6)+(1*2)=89
89 % 10 = 9
So 586-62-9 is a valid CAS Registry Number.

Sustainable p-cymene and hydrogen from limonene
Martin-Luengo,Yates,Rojo, E. Saez,Huerta Arribas,Aguilar,Ruiz Hitzky
, p. 141 - 146 (2010)
A fine chemical intermediate in a wide range of chemical processes, p-cymene, has been obtained from Limonene, solids based on a natural clay (sepiolite) modified with sodium, nickel, iron or manganese oxides and programmable focalised microwaves. The process has the added bonus of one mol of hydrogen being produced per mol of limonene converted to p-cymene.
Aromatization of Hydrocarbons y Oxidative Dehydrogenation Catalyzed by the Mixed Addenda Heteropoly Acid H5PMo10V2O40
Neumann, Ronny,Lissel, Manfred
, p. 4607 - 4610 (1989)
The mixed addenda heteropoly acid H5PMo10V2O40 dissolved in 1,2-dichloroethane with tetraglyme, forming the (tetraglyme)3-H5PMo10V2O40 complex, catalyzes the aromatization of cyclic dienes at moderate temperatures in the presence of molecular oxygen.Dehydrogenations of exocyclic dienes such as limonene show that dehydrogenation is preceded by isomerization to their endocyclic isomers.Aromatization takes place by succesive one-electron transfers and proton abstractions from the organic substrate to the heteropoly acid, the latter being reoxidized by dioxygen coupled with the formation of water.
Preparation method of isopentylene
-
Paragraph 0031-0050, (2021/11/10)
The method comprises the following steps: taking dipentene as a raw material, and using acetic acid in a high-pressure carbon dioxide environment. Isoterpinene is prepared by reacting acetate and an axial chiral nitrogen-containing compound as a catalyst. The axial chiral nitrogen-containing compound is one or more of an axial chiral nitrogen-containing binaphthyl or biphenyl compound. The selectivity and yield of terpinene are high.
Thioderivatives of Resorcin[4]arene and Pyrogallol[4]arene: Are Thiols Tolerated in the Self-Assembly Process?
Nemat, Suren J.,Tiefenbacher, Konrad
supporting information, p. 6861 - 6865 (2021/09/14)
Three novel thiol bearing resorcin[4]arene and pyrogallol[4]arene derivatives were synthesized. Their properties were studied with regards to self-assembly, disulfide chemistry, and Br?nsted acid catalysis. This work demonstrates that (1) one aromatic thiol on the resorcin[4]arene framework is tolerated in the self-assembly process to a hexameric hydrogen bond-based capsule, (2) thio-derivatized resorcin[4]arene analogs can be covalently linked through disulfides, and (3) the increased acidity of aromatic thio-substituent is not sufficient to replace HCl as cocatalyst for capsule catalyzed terpene cyclizations.
