Abstract:

A concise, transition metal-free four-step synthetic pathway has been developed for the synthesis of tetracyclic heterosteroidal compounds, 14-aza-12-oxasteroids, starting from readily available 2-naphthol analogues. After conversion of 2-naphthols to 2-naphthylamines by the Bucherer reaction, subsequent selective C-acetylation was achieved via the Sugasawa reaction and reduction of the acetyl group using borohydride, which resulted into the corresponding amino-alcohols. The naphthalene-based amino-alcohols underwent double dehydrations and double intramolecular cyclization with oxo-acids lead

Thesis (MTech(Chemistry))--Cape Technikon, Cape Town,1995<br>The naphtho[2,3-c]pyran occurs frequently in nature as derivatives of the 5,10 quinones.

The possibility of appropriately substituted compounds functioning as bioreductive alkylating agents provides a logical model that has a great deal of predictive power.

The ultrafast nonlinear optical properties of Polycyclic aromatic hydrocarbon (PAHs) based benzo[b]perylene derivative named as benzo[b]naphtho[1,2,3,4-pqr]perylene (BNP) are studied using femtosecond Z-scan at 800 nm. A strong three-photon absorption coefficient of 0.56×10-5 cm3/GW2 was observed.

Abstract:

Direct use of naphtha in compression ignition (CI) engines is not advisable because its lower cetane number negatively impacts the auto ignition process. However, engine or fuel modifications can be made to operate naphtha in CI engines. Enhancing a fuel’s auto ignition characteristics presents an opportunity to use low cetane fuel, naphtha, in CI engines. In this research, Di-ethyl ether (DEE) derived from ethanol is used as an ignition enhancer for light naphtha. With this fuel modification, a “drop-in” fuel that is interchangeable with existing diesel fuel has been created. The ignition cha

Abstract:

To integrate or not to integrate petrochemicals – that is the question posed by this paper for Saudi Arabian oil refineries. The viability of combining domestic oil refining and petrochemical activities is investigated using an energy system model for Saudi Arabia. Two scenarios are examined: one allows intermediate naphtha streams to flow freely from refineries to petrochemical equipment, while the other prevents petrochemical units from using intermediate naphtha. The modeling analysis reveals present cost savings of $10 billion from 2023 to 2060 due to integration. Since two Saudi refinerie
