The title compound, C(17)H(15)BrOS, was prepared by the Lewis acid-catalysed reaction of 2,4-dimethyl-phenol with 4'-bromo-2-chloro-2-(methyl-sulfan-yl)acetophenone. The 4-bromo-phenyl ring is rotated slightly out of the benzofuran plane, making a dihedral angle of 8.4 (1)°. The crystal structure is stabilized by a CH(2)-H⋯π inter-action between the 5-methyl group and the benzene ring of the be...

In this research, a response surface methodology (RSM) was used to investigate the effects of independent parameters (pH, contact time, temperature, adsorbent dosage, and initial concentration of pollutant), their simultaneous interactions, and quadratic effects on crystal violet adsorption onto two starch based materials in the form of batch experiments. The characterizing results indicated th...

Article history: Received 16 January 2017 Accepted 16 January 2017 Available online 19 January 2017 hypothesis. We are currently doing a clinical trial Minami Aoyama Eye Clinic in Tokyo, Japan using a violet light-emitting desktop light and violet light-transmitting eyeglasses (Clinical trial number: UMIN000021897). Also, a randomized clinical trial is underway on violet light transmitting eyeg...

Organic colourants have important applications in many fields. Their photostability is an characteristic. Several methods to study photodegradation were compared this work. Eosin Y (C.I. Generic name: Acid Red 87, EY) and crystal violet Name: Basic Violet 3, CV) used as test compounds, both solution dyed on silk. Commonly applied included, viz. Xenotest, Microfading-Tester, light-box (Spectroli...

A reworkable resin, which is degradable after use, was developed for application as a dental resin with an enhanced stability. dimethacrylate monomer containing ketal linkage in the molecule used monomer. The successfully cured by blue light irradiation (470-nm light) using camphorquinone/amine photoinitiating system. resins were degraded presence of UV- and violet-light sensitive photoacid gen...

A new instrument dedicated to the kinetic study of low-temperature gas phase neutral–neutral reactions, including clustering processes, is presented. It combines a supersonic flow reactor with vacuum ultra-violet synchrotron photoionization time-of-flight mass spectrometry. photoion–photoelectron coincidence detection scheme has been adopted optimize particle counting efficiency. The characteri...
