Discoloration of Hydrotreated Naphthenic Rubber Base Oil at High Temperature

Abstract

In this article, the reasons for discoloration of hydrotreated naphthenic rubber base oil under high temperature were studied in detail. In order to define compositional factors associated with the color deterioration, firstly liquid-solid chromatography was used to separate hydrotreated naphthenic rubber base oil into five different fractions, i.e., saturates, monoaromatics, diaromatics, polyaromatics, and polars. Then color change of each fraction was evaluated under high temperature. The results of the test indicate that polyaromatics and polars are the main precursor of color and deposits, respectively, and the composition of polyaromatics was characterized by elemental analysis, gas chromatography mass spectrometry (GC-MS) and atmospheric pressure chemical ionization mass spectrometer (APCI/MS).

Compositional Changes of Hydrotreated Naphthenic Rubber Base Oil Under High Temperature

Abstract

This article discusses the compositional changes of hydrotreated naphthenic rubber base oil under high temperature. First, we adopted liquid–solid chromatography to separate the initial oil and the heated oil into three different fractions (i.e., saturates, aromatics, and polars). Next, each fraction's compositional change was respectively evaluated through a series of instrument technology including gas chromatography-mass spectroscopy (GC-MS), infrared spectroscopy (IR), and x-ray photoelectron spectroscopy (XPS). The results show that under high temperature, the heated sample exhibits a decrease in the saturate and aromatic fractions concomitant with an increase in the polar fraction. For saturates, the content of alkanes in the heated sample exhibits a relatively substantial decrease. On the other hand, the content of cycloalkanes shows a little increase in trend, and the heated oil sample exhibits a decrease in aromatics. Regarding polars, a relatively large amount of oxygen-containing compounds such as hydroxyl, carbonyl, and carboxyl groups was formed under high temperature. XPS data show that a type of S 2pa compounds in the initial oil disappears and could be converted to SO42?. A part of polar compounds in the heated oil could come from aromatic thermo-oxidation in the initial oil.
