General Description

2-Bornene, also known as alpha-pinene, is a bicyclic monoterpene hydrocarbon compound that occurs naturally in certain essential oils, particularly from coniferous trees. It is a colorless liquid with a pine-like odor and is commonly used as a fragrant additive in perfumes and household cleaning products. 2-Bornene is also utilized in the production of synthetic camphor, synthetic pine oil, and as a precursor in the synthesis of other organic compounds. It is a volatile compound that can easily react with other chemicals, making it an important building block in various industrial and manufacturing processes. Additionally, it has been studied for its potential medicinal properties, including anti-inflammatory, antimicrobial, and bronchodilator activities. However, it can also be irritant to the respiratory system and skin when inhaled or in direct contact, so proper handling and precautions are necessary when working with this chemical.

Synthesis, Characterization, and Catalytic Activity of NAPO-5 and NAPO-11

Nickel-substituted aluminophosphate molecular sieves (NAPO-5 and NAPO-11) were synthesized hydrothermally using triethylamine and dipropylamine as templates.Structures were confirmed by X-ray powder pattern, and unit cell parameters calculated by a standard least square refinement technique.The isomorphous substitution of nickel in the aluminophosphate framework is evidenced by the considerable increase in unit cell volume compared to unsubstituted AlPO4-5 and AlPO4-11.In addition, electron spin resonance and diffuse reflectance spectra were carried out to produce supporting evidence for the isomorphous substitution of nickel.Acidity was determined by TPD-TGA method which shows two types of acid sites.Symmetry and asymmetry vibrations were obtained from infrared spectra.Chemical analysis by ICP and BET surface area are also reportedd.The physicochemical properties of the catalysts were correlated towards isomerization of camphene at various (WHSV)-1 values and temperatures.The products formed are tricyclene and 2-bornene and the selective formation of tricyclene was achieved over, these catalysts.

Catalytic Transformation of camphene over Aluminophosphate-based Molecular Sieves

Electronic Effects of Polar Substituents in the Gas Phase Unimolecular Elimination of 4-Substituted Isobornyl Acetates

The rates of gas-phase elimination of a series of 4-substituted isobornyl acetates have been measured in the presence of propene between 209-370 deg C and within a pressure range 37-153 Torr; a static system with seasoned vessels was used.The reaction are unimolecular, homogeneous, and obey a first-order rate law; electron-withdrawing substituents at C(4) cause a diminution in the elimination rate, such that ρ1 -0.69 in a Hammett treatment.The temperature dependence of the rate coefficients is illustrated for the Arrhenius equation for isobornyl acetate: logk/s-1=(12.82+/-0.13)-(189.2+/-1.5)kJmol-1/2.303RT.The results are consistent with a cyclic transition state in which C(2)-O cleavage is more advanced than that of C(3)-H.The major primary product of elimination of isobornyl acetate is bornylene, which partially isomerises to camphene and tricyclene under the reaction conditions.Bornylene also undergoes a retro-Diels-Alder reaction to yield the trimethylcyclopentadiene and ethylene.
