General Description

3,5-Diisopropylcatechol, also known as DIPC, is a chemical compound with the molecular formula C11H16O2. It is a derivative of catechol and is used primarily as a stabilizer in the formulation of industrial coatings and polyurethane foams. DIPC is known for its ability to inhibit the oxidation of polymers, which helps to extend their shelf life and improve their overall performance. It is also used as an antioxidant in the production of rubber and other elastomers. Additionally, DIPC has applications in the synthesis of pharmaceuticals and as a reagent in organic chemistry reactions. The compound is a colorless solid and is soluble in organic solvents such as ethanol and acetone. However, it is sparingly soluble in water. DIPC is classified as a hazardous substance and should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system upon exposure.

Synthesis and structure of 5,7-diisopropyl-2-(quinolin-2-yl)-1,3-tropolone derivatives

A synthetic procedure towards 4,6-diisopropyl-3-nitro-1,2-benzoquinone was elaborated. Based on this benzoquinone, a series of novel 5,7-diisopropyl-2-(quinolin-2-yl)-1,3-tropolones and 5,7diisopropyl-2-(quinolin-2-yl)-4-nitro-1,3-tropolones were derived. Molecular structure of 2-(4-chloro-8-methylquinolin-2-yl)-5,7-diisopropyl-1,3-tropolone was established by X-ray diffraction analysis. Energetic and structural characteristics of isomeric 5,7-diisopropyl-2-(quinolin-2yl)-1,3-tropolones and 5,7-diisopropyl-2-(quinolin-2-yl)-4-nitro-1,3-tropolones in the gas phase and in the polar solvent were calculated by quantum chemistry method (PBE0/6-311+G(d,p)).

Sonocatalytic removal of naproxen by synthesized zinc oxide nanoparticles on montmorillonite

ZnO/MMT nanocomposite as sonocatalyst was prepared by immobilizing synthesized ZnO on the montmorillonite surface. The characteristics of as-prepared nanocomposite were studied by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM) and X-ray diffraction (XRD) techniques. The synthesized samples were used as a catalyst for sonocatalytic degradation of naproxen. ZnO/MMT catalyst in the presence of ultrasound irradiation was more effective compared to pure ZnO nanoparticles and MMT particles in the sonocatalysis of naproxen. The effect of different operational parameters on the sonocatalytic degradation of naproxen including initial drug concentration, sonocatalyst dosage, solution pH, ultrasonic power and the presence of organic and inorganic scavengers were evaluated. It was found that the presence of the scavengers suppressed the sonocatalytic degradation efficiency. The reusability of the nanocomposite was examined in several consecutive runs, and the degradation efficiency decreased only 2% after 5 repeated runs. The main intermediates of naproxen degradation were determined by gas chromatography-mass spectrometry (GC-Mass).
