Search for a Catalyst for Alkylation of Phenols by Olefins

Alkylphenols (AP( containing branched alkyl groups in the ortho position to the OH group and their various functional derivatives can effectively protect hydrocarbon fuels, lube oils, rubber, and other polymer materials from oxidation [ ]1–3]. They are obtained with high (90%) selectivity, usually by reacting phenol with olefins in the presence of aluminum triphenolate as catalyst [4].     

Methods for modification of track-etched membranes designed for separation of biological objects

The existing and promising methods for modification of track-etched membranes are considered and analyzed; they are compared for subsequent separation of biological objects. On the basis of the results of comparative analysis, the simplest and most producible method of modification of track-etched membranes has been chosen.

Requirements for Vacuum Resids for Production of Oxidized Paving Asphalts

Correct selection of feedstock predetermines the quality of oxidized asphalts. However, the active standards do not allow making such a selection. The requirements for vacuum resids for production of oxidized paving asphalts should be differentiated as a function of the nature of the crude oil refined and the grade of the binders obtained. A method is developed and the requirements are determined for vacuum resids as applied to the conditions of Saratov Refinery. The necessity of improving the active standard for viscous paving asphalts is noted.     

海洋平台冰力记录分量拾遗

本文研究了海洋平台冰力记录分量的拾遗问题。对过去常采用的插值法进行了讨论,指出了其不足之处,提出了一种建立在最小二乘法基础之上的冰力记录分量拾遗方法。其算例表明,本文方法具有冰力记录分量拾遗精度较高,能够充分利用已有的完整冰力记录等特点。
