Tetrahydrocannabivarin
Tetrahydrocannabivarin (THCV, THV, O-4394, GWP42004) is a Homology (chemistry), homologue of tetrahydrocannabinol (THC) having a propyl (3-carbon) side chain instead of a pentyl (5-carbon) group on the molecule, which makes it produce very different effects from THC. Natural occurrence THCV is prevalent in certain central Asian and southern African strains of ''Cannabis''. Chemistry Similar to tetrahydrocannabinol, THC, THCV has 7 possible double bond isomers and 30 stereoisomers (see: Tetrahydrocannabinol#Isomerism). The alternative isomer Δ8-THCV is known as a synthetic compound with a code number of O-4395, but it is not known to have been isolated from ''Cannabis'' plant material. ] Description Plants with elevated levels of propyl cannabinoids (including THCV) have been found in populations of ''Cannabis sativa'' L. ssp. ''indica'' (= ''Cannabis indica'' Lam.) from China, India, Nepal, Thailand, Afghanistan, and Pakistan, as well as southern and western Africa. THCV ...

The Horsemen's Voice
''The Horsemen's Voice'' (THV) is an independent, privately owned magazine founded in 1982 by Sallie Pennybacker as the newsletter for the New Mexico Horse Council, in New Mexico, USA. She published the magazine for 17 years. ''THV'' grew beyond the New Mexico Horse Council and became a magazine. For a time during 2000–2004 there was an additional, online newsletter A newsletter is a printed or electronic report containing news concerning the activities of a business or an organization that is sent to its members, customers, employees or other subscribers. Newsletters generally contain one main topic of int ..., but this caused confusion, with many newsletter subscribers thinking the newsletter and magazine were one and the same. The magazine's tag line has varied, including "New Mexico's All Breed, All Discipline horse magazine" and "New Mexico's Horse Magazine". Color printing of the cover and some pages was introduced in 2006. An important part of the magazine is its fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetrafluoroethylene
Tetrafluoroethylene (TFE) is a fluorocarbon with the chemical formula C2 F4. It is the simplest perfluorinated alkene. This gaseous species is used primarily in the industrial preparation of fluoropolymers. Properties Tetrafluoroethylene is a colorless, odorless gas. Like all unsaturated fluorocarbons, it is susceptible to nucleophilic attack. It is unstable towards decomposition to carbon and carbon tetrafluoride () and prone to form explosive peroxides in contact with air. Industrial use Polymerization of tetrafluoroethylene produces polytetrafluoroethylene (PTFE) polymers such as Teflon and Fluon. PTFE is one of the two fluorocarbon resins composed wholly of fluorine and carbon. The other resin composed purely of carbon and fluorine is the copolymer of TFE with typically 6–9% hexafluoropropene (HFP), which is known as FEP (fluorinated ethylene propylene copolymer). TFE is also used in the preparation of numerous copolymers that also include hydrogen and/or oxygen, includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexafluoropropylene
Hexafluoropropylene is the fluoroalkene with the formula CF3CF=CF2. It is the perfluorocarbon counterpart to the hydrocarbon propylene. It is mainly used to produce copolymers with tetrafluoroethylene. Hexafluoropropylene is used as a chemical intermediate. Preparation Hexafluoropropylene can be produced by pyrolysis of tetrafluoroethylene: :3CF2=CF2 → 2CF3CF=CF2 It can also be prepared from chlorodifluoromethane, or produced from various chlorofluorocarbons Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated hydrocarbons that contain carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propan ....

1,1-Difluoroethylene
1,1-Difluoroethylene, also known as vinylidene fluoride, is a hydrofluoroolefin. It is a flammable gas. Global production in 1999 was approximately 33,000 metric tons. It is primarily used in the production of fluoropolymers such as polyvinylidene fluoride. Preparation 1,1-Difluoroethylene can be prepared by elimination reaction from a 1,1,1-trihaloethane compound, for example, loss of hydrogen chloride from 1-chloro-1,1-difluoroethane:. : or loss of hydrogen fluoride from 1,1,1-trifluoroethane: : See also * 1,2-Difluoroethylene *Perfluoroisobutene Perfluoroisobutene (PFIB) is the perfluorocarbon counterpart of the hydrocarbon isobutene and has the formula (CF3)2C=CF2. An alkene, it is a colorless gas that is notable as a highly toxic perfluoroalkene. Few simple alkenes are as toxic. Safet ...
