Abstract:
When synthetizing 2 - hydroxy - 6 - naphthoic acid with 2 - naphthol as raw material , we use a variety of methods to characterize and analyze the intermediates and target product . Through melting point method, the melting point of HNA we synthetized is showed to be slightly lower than standard samples. High performance liquid chromatographic shows that the purity of 2 - methoxy - 6 - naphthoic acid 2 - hydroxy - 6 - naphthoic acid reach up to 81.98% and 99.0% respectively. The purity of 2-hydroxyl-6-naphthoic acid is showed to be 97.1% with ultraviolet spectrophotometry.

Abstract:
Poly(6-hydroxy-2-naphthoic acid), poly(2,6-HNA), was synthesized by three different methods: polycondensation of 6-acetoxy-2-naphthoic acid, or its trimethylsilyl ester, and polycondensation of free 6-hydroxy-2-naphthoic acid with acetic arnhydride in an 'one-pot procedure'. The last method gave whiskers only when a monomer of high purity was used. Different temperatures (350 or 400C) and reaction media tMarlotherm-S, Marlotherm-SCB or Santotherm) were applied. Furthermore, the reaction time and monomer concentration were varied. 6-Acetoxy-2-naphthoic acid yielded whiskers only at concentratio

These compounds have a large (negative) resonance energy, resulting in a thermodynamically stable structures. PAHs may also contain alkyl- and nitro-substituent groups. The complexity in these molecules can be generated by substituting the aromatic carbon atom with nitrogen, oxygen or sulfur, giving rise to heterocyclic PAHs.

Abstract:
Abstract Canadian Athabasca oilsand bitumen crudes, characterized as corrosive by the classical naphthenic model, are producing negligible naphthenic acid corrosion in crude and vacuum units after more than 50 years of cumulative operation. A new theory proposes that the corrosivity of naphthenic acids in Athabasca oilsand bitumen crudes is a function of its molecular weight, molecular structure, true boiling point, reactive sulfidic species, and local environment. The concept of α (bad type) and β (good type) naphthenic acids is introduced. The α naphthenic acids are characterized as corrosiv

Abstract:
Abstract Naphthenic acids and sulfur containing compounds in crude oils are corrosive at high temperature and have been strong concerns for potential corrosion damage in the atmospheric distillation units, vacuum distillation units, transfer lines, and side cut piping in the refining industry. Naphthenic acid and sulfur compound induced corrosion is influenced by a number of critical factors including concentration and molecular characteristics of naphthenic acids and sulfur compounds, process temperature, oil fluid velocity and wall shear stress. This paper will comparatively and comprehensiv
