Bicyclo[3.1.1]hept-2-ene, also known as norbornene, is a cyclic olefin with the molecular formula C7H12. It is a colorless liquid with a strong, pungent odor and is widely used as a monomer in the production of various polymers, such as norbornene-based resins and copolymers. Norbornene is known for its unique bicyclic structure, which consists of two carbon rings fused together, with one of the rings being a cyclopropane ring. This structure imparts unique properties to the compound, such as high thermal stability and resistance to degradation. It is also used as a solvent and a chemical intermediate in the synthesis of various pharmaceuticals and agrochemicals.

4889-83-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4889-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4889-83:
(6*4)+(5*8)+(4*8)+(3*9)+(2*8)+(1*3)=142
142 % 10 = 2
So 4889-83-2 is a valid CAS Registry Number.

Acidic property of FSM-16

Yamamoto, Takashi,Tanaka, Tsunehiro,Funabiki, Takuzo,Yoshida, Satohiro

, p. 5830 - 5839 (2007/10/03)

Siliceous FSM-16 possesses acid sites to catalyze but-1-ene isomerization to produce but-2-ene (cis/trans = 1.4-1.7) at 323 K and 2,6,6- trimethylbicyclo[3.1.1]hept-2-ene (α-pinene) isomerization at 303 K. Catalytic activity was dependent upon heat treatment and reached a maximum at 673 K. The maximum acid strength was invariably H0 = -3.0 independent of the pretreatment temperatures. The acidity was much reduced by calcination at higher temperatures, but restored by water treatment at 353 K as long as the FSM-16 retained its structure.
