The polyamine (PA) was prepared by condensation of 1,4-bischloromethyl benzene and benzidine. The PA was then treated with cyanuric chloride at 0°C followed by reaction with 5-amino-8-Hydroxyquinoline in THF in conc. NaOH (PH 9-10) at room temperature for 8 hrs. The resultant polymer designated as polyamine-s-triazine-5-amino8-Hydroxyquinoline (PATHQ) was characterized by elemental analysis, IR...

In the last decade, adsorption has been used to minimize the pollution caused by dyes, which represents a serious environmental problem. In this context, this work reports the preparation of phthalic anhydride-modified cellulose (PhCel), through the reaction of cellulose (Cel) with phthalic anhydride (Ph). The efficiency of the reaction was observed by elemental analysis, Fourier Transform Infr...

In this paper we elected to nitrate p-xylene because this compound has only one mononitro- and trinitro- isomer. Trinitro-p-xylene was used as a starting material for the synthesis of other compounds in subsequent work. The mononitration of p-xylene can be easily carried out at 30 degrees C. Nitro-p-xylene is easily nitrated to dinitro-p-xylene at a temperature of 80 degrees C. The trinitro-p-x...

The aim of this study is to prepare a solid fuel from the most abundant biomass of Morocco that can be used by the local population, and in particular by the rural ones, instead of the wood of forest, which is less available and its exploitation is negative for the environment. Esparto is the most available biomass, with a production of 560000 tons annually of dry matter approximately. However,...
