Abstract:

Blends of 4,4′-bisisomaleimidodiphenyl methane (VS) with structurally different diphenols are made in 1:1 molar ratio and thermally polymerized. Thermogravimetric studies of the cured materials show that the thermal stability, the degradation pattern and the char yield are much dependent on the structure of the diphenol that is used for blending. The decreased thermal stability of materials from the blends is attributed to decreased cross links owing to the opening of the isomaleimide rings by diphenols during thermal polymerization. The materials with trimethylphenylindane and tetramethylspir

Abstract:

Polymerization of coffee grounds oil with Diphenyl Methane 4,4 Diisocyanate (MDI), epoxidation with performic acid and H2SO4(p) catalyst at 40-45°C, followed by hydrolysis to obtain polyols. The synthesis was carried out by reacting the polyol with Diphenyl Methane 4,4 Diisocyanate (MDI) with a ratio (polyol: MDI) 9:1; 8:2 ; 7:3 ; 6:4 ; 5:5 (v/v) in dichloromethane solvent. Each was characterized and the density values were 0.9086 gr/cm to 0.4979 gr/cm-1, the tensile strength and elongation values were 0.113 Mpa to 0.299 Mpa and 3.23% to 6.85%, respectively.

Abstract:

Thyromimetics, whose physicochemical characteristics are analog to thyroid hormones (THs) and their derivatives, are promising candidates as novel therapeutics for neurodegenerative and metabolic pathologies. In particular, sobetirome (GC-1), one of the initial halogen-free thyromimetics, and newly synthesized IS25 and TG68, with optimized ADME-Tox profile, have recently attracted attention owing to their superior therapeutic benefits, selectivity, and enhanced permeability. Here, we further explored the functional capabilities of these thyromimetics to inhibit transthyretin (TTR) amyloidosis.

These compounds are known contact sensitizers in phenol-formaldehyde resins (P-F-R).

Abstract:

In epoxy based polymeric nonlinear optical (NLO) materials, the nonlinear optically active moiety forms crosslink between polymer chains. Some of the important moieties include 4, 4'diamino diphenyl sulfone (DADS). We have examined second harmonic generation (SHG) in DADS and have compared it with 4, 4'diamino diphenyl methane (DADM). The geometry optimization suggests that both molecules have Λ-shaped structure. The theoretical calculations as well as experimental observations of SHG in both the molecules suggest the suitability of DADS over DADM for making polymeric NLO materials.

Abstract:

Difluoro(phenylsulfanyl)methane (PhSCF2H) was found to undergo a reaction with aromatic compounds mediated by SnCl4, through a thionium intermediate characterized by NMR and TD-DFT analyses, leading to the formation of a mixture of S,S′-diphenyl dithioacetal and aromatic aldehyde which, after oxidative hydrolysis, provides the aromatic aldehyde in good to excellent yields. The salient feature of the present work is the reaction of activated aromatic compounds containing a deactivating ester functional group, leading to the formylated products in good yields.

Des substrats naphtaléniques, solubles dans l'eau, permettent de stocker l'oxygène singulet efficacement puisqu'ils fixent (1)O:(2) entre 0 et 20°c, et sont totalement régénérés par thermolyse à 40°c, en libérant l'oxygène dont 50% est à l'état singulet.
