Aldol condensation is an important synthetic method widely used in organic synthesis. Development of catalytic methods that avoids the production stoichiometric by-products while maintaining high levels control available from processes provides atom-economical alternative for these transformations. Indeed, numerous catalysts aldol reaction have been reported recent years, including enzymes, antibodies, organometals, organocatalysts, and small molecules. The direct most employed by chemists...
Locally sourced waste cooking oil (WCO) was successfully base-catalyzed and transesterified with methanol into biodiesel to produce biostimulant (nitrobenzene) formulations replace high-risk carrier solvents. Ideal synthesis conditions were composed of 1% NaOH, MeOH/oil molar ratio (6:1), reaction temperature (65 °C), a 3 h mixing rate, 97–98% yields. Gas chromatography–mass spectrometry (GC-MS) analysis identified five fatty acid methyl esters (FAMEs) including palmitic, linoleic, oleic,...
Multi-location supervised field trials were conducted in India at four locations of the All Network Project (AINP) on Pesticide Residues to study persistence, dissipation and risk assessment flubendiamide deltamethrin cucumber (Cucumis sativus). resulting from three spray applications a combination formulation (flubendiamide 90% + 60%, 150 SC) recommended (22.5 15 g a.i./ha) double (45 30 dose analysed. On basis persistence studies, half- life (T1/2) varied 1.40 2.98 (recommended dose) 1.55...
Abstract Background: Pesticide residue in fish is a global food safety concern. However, very few validated methods are available targeting simultaneous analysis of multiple classes pesticides. Objective: The aim this study was to validate quick, easy, cheap, effective, rugged, and safe workflow–based method for the quantitative determination multiclass pesticides matrix using GC-MS determination. Method: sample extracted with acetonitrile, cleanup involved dispersive solid-phase extraction...
Abstract When the asymmetric aldol reactions are catalyzed by amino acids in water, a certain amount of organic solvents such as ethanol, tetrahydrofuran still had to combine with water dissolve aldehydes and promote reaction. But protect environment our aim is completely eliminate use solvent, therefore we have started investigate new system for reaction without using any solvents. Mainly solvent form homogeneous phase all reactants which not possible if it makes most substances spasingly...
Abstract Advances in science and technology are promoting eco-friendly synthesis routes, green chemicals, non-hazardous solvents. A suitable method for the of 2-(prop-2-ynyloxy) benzaldehyde was developed using three different aqueous micellar media. The targeted product ether is completely immiscible water, but combination with interface active surfactants it has been possible to produce hydrophobic organic compound water. Micelles function as a pseudocellular environment isolate species...
The presence of undesirable substances, including pesticides (xenobiotics) in betel leaf (Piper betel), is a great concern for consumers because it chewed and consumed directly. To protect the consumer's health, modified QuEChERS method monitoring purposes subsequent decontamination process has been developed. goal this work was to establish multi-residue analytical nonpermitted organophosphorus pesticide residues leaf, as well cost-effective cleaning strategies. homogenized 15 g samples (20...
Chemo-selective heterogeneous catalytic hydrogenation was employed to synthesise 6-amino-N-methyl-2-quinolone (AMQ) and 6-amino-N-ethyl-2-quinolone (AEQ) establish its structure-activity relationship (SAR) by 1H NMR,13C NMR, FT-IR, LC-MS/MS. AMQ (MIC = 18.2, 16.5 mg/mL) AEQ 19.2, 20.5 mg/mL), were more effective against Aspergillus niger flavous. Both tested on tomato (Solanum lycopersicum L.) plants assess residual profiles, dissipation patterns, yield effects. Acetonitrile methanol...
