[ 1 ] - Determination of Sulfonation Conditions of HAB as a By-product of Linear Alkylbenzene Production
Heavy alkylated benzene (HAB), which is a by-product in linear alkylbenzene (LAB) production by UOP process, is separated by distillation from LAB and consists of a range of components such as polyalkylbenzenes, diphenylalkanes, alkyl tetralins, and alkylindans. The products of sulfonation of HAB or its distillation cuts are of wide industrial applications such as emulsifiers, dispersants in lu...
[ 2 ] - مطالعه آزمایشگاهی و مدلسازی سینتیکی تشکیل هیدرات کربندیاکسید در حضور مایعات یونی
در این پژوهش، تأثیر دو مایع یونی 1- بوتیل 3- متیل ایمیدازولیوم تترافلوئوروبورات [Bmim][BF4] و 1- بوتیل 3- متیل ایمیدازولیوم متیل سولفات [Bmim][MS] بر سینتیک تشکیل هیدرات کربندیاکسید بررسی شده است. در عمل و در فشار اولیه bar 35 و در حضور این دو مایع یونی با غلظت جرمی، مشاهده شد که [Bmim][BF4] و [Bmim][MS] 6/0% با کاهش زمان القاء و هستهزایی، موجب تسریع فرآیند تشکیل هیدرات کربندیاکسید شده و ...
[ 3 ] - Topanol A as an Antioxidant for Jet Fuel: Preparation and Application
Topanol A is a phenolic antioxidant additive, which is used in storage tanks for jet fuels produced in the petroleum refineries throughout the country. Topanol A mostly consists of 2,6-di-t-butylphenol. The conventional methods for the preparation of this compound involve ortho-alkylation of phenol using 2-methylpropene (isobutylene) as the alkylating agent. The compound has been prepared by or...
