Tert-butylated investigated in terms of conversion and selectivity for the desired product under mild conditions.

(Abstract maximum 300 words)

Keywords: alkylation; dodecatungstophosphoric acid; nanoparticle; tert-Butylation



Tert-butylation of phenol is an industrially important reaction and alkylated phenols are widely used for a variety of applications such as antioxidants, herbicides, insecticides, and polymers [1]. They are conventionally prepared by reacting phenol with pure isobutylene gas or C4 fraction of naphtha using a liquid acid catalyst, which gives wide product distribution. In general, tert-butylation of phenols is carried out in a homogeneous medium using sulphuric acid, phosphoric acid, aluminium chloride–boric acid or boron trifluoride as a catalyst [2]. The use of conventional Friedel–Crafts catalysts gives rise to many problems concerning handling, safety, corrosion, and waste disposal. Therefore, considerable efforts have been made for the development of suitable heterogeneous solid acid catalysts [3]. The current processes use highly polluting and hazardous catalysts. Although many commercial ion exchange resins exhibits high activity for the tert-butylation of phenol and substituted phenols with isobutylene, their lower thermal stability limit their industrial application. Various solid acid catalysts have been reported in the literature for tert-butylation of phenols [4-8]. Most of the solid acid catalysts reported are active and the most important problem is the selectivity for the desired product [9].


2.1. Preparation of DTP included silica nanoparticle

The modified version of DTP included  silica nanoparticle was prepared by sol–gel technique followed by steaming. In a typical procedure, 30wt % DTP/SiO2 was prepared by dissolving

2.2. Characterization

Powder X-ray diffraction patterns were recorded using a Rigaku 2000 diffractometer equipped with a Cu-Kα radiation (λ = 1.5418 Å) from 2θ = 2.5 to 60° at a scan rate of 2°/min


3.1.Surface area measurements

The surface area of the unsteamed 30 wt % DTP/SiO2 is only 27 m2/g whereas after steaming, it increases drastically up to 10 times, i.e. 30 wt % DTP/SiO2 is 277 m2/g. During the

3.2.TEM analysis

            TEM micrographs of 30 wt % DTP/SiO2 sample prepared before and after steaming are reported in Fig. 2.
