Department of Chemistry, University of Delhi, Delhi-110 007 <em>Manuscript received 4 December 1990, accepted 31 May 1991</em> Kinetics of the reaction between phloroglucinol and acetophenone was investigated at different temperatures (30-45°) in methanol and different hydrochloric acid concentration (0.024-0.710 <em>M</em>) were used. The reaction was promoted using thioglycollic acid (TGA) and the functionality of phloroglucinol was also taken into account. Reaction was found to obey second order kinetics. Activation parameters were calculated. The reaction was also carried out In s

Abstract:

An alternative for the conservation of orchid species threatened with extinction is the seeds preservation for long periods by cryopreservation. This work aimed to evaluate the influence of cryogenic solutions on the orchids Epidendrum radicans and Arundina bambusifolia seeds cryopreservation in liquid nitrogen. Seven treatments were performed: 0.4 M sucrose; 2 M glycerol; PVS1; PVS2; PVS3; PVS2 + 1% phloroglucinol and the control. After liquid nitrogen removal, half of the seeds were subjected to tetrazolium test, and another half was in vitro cultured. After 30 days seed germination was eval

Abstract:

The Brazilian Caatinga houses a number of cacti species, which are considered endangered due to human influence. Two of them, Melocactus zehntneri Braun ex Ritter f. and Cereus gounellei Luetzelb ex Schum k., are endemic of the Brazilian Caatinga. Cryopreservation can provide a means for long-term preservation of endangered plant material. The aim of this study was to evaluate the efficiency of cryoprotectants for the cryopreservation of seeds from these two species. The treatments consisted of immersing seeds in different cryoprotectant solutions and vitrification solutions before storage in

Abstract:

In response to the near-threatened status of Handroanthus impetiginosus, primarily due to habitat loss and illegal logging, this study examines how X-ray imaging and cryopreservation impact the seed quality and viability essential for conservation. Seeds initially had a moisture content of 12.3%, reduced to 6.5% through desiccation. X-ray imaging allowed for detailed visualization of internal structures, identifying seeds as normal, abnormal, or dead based on damage and development. Normal seeds consistently germinated and produced healthy seedlings, while those with internal damage or excessi

Abstract:

Many phenolic compounds are related to the group of toxic substances, the occurrence of which in wastewater has a negative impact on the environment. In addition to extraction, biochemical, and membrane methods for the isolation of hydroxybenzenes from aqueous media, sorption methods using active carbon, nonionic polymers, and ion-exchange materials are also actively used. The purpose of this work was to establish the features of the sorption of phenol, resorcinol and phloroglucinol from aqueous solutions with FIBAN fibers. Sorption was studied under static conditions at a temperature of 298 K

Abstract:

The DFT/B3LYP quantum-chemical method has been used to simulate the structure of 2-((2-hydroxyphenyl) diazonyl) benzene-1,3,5-triol (L1) and 2-((2-hydroxy-4-nitrophenyl) diazonyl) benzene-1,3,5-triol (L2) molecules. The spatial and electronic structure of molecules in various tautomeric forms was determined. It was shown that the stability of these compounds is primarily due to the presence of strong intramolecular hydrogen bonds (IHB), which form six-membered cycles, and the isomerism of the molecule, which assume the formation of IHB. The structures where IHB form five-membered cycles, are l

Abstract:

The objective was to evaluate the use of cryogenic solutions in cryopreservation Sinningia leucotricha seeds by the vitrification method in liquid nitrogen. The treatments were: T1 - control: without cryoprotective solution; T2 - PVS1; T3 - modified PVS1; T4 - PVS2; T5 - modified PVS2; T6 - PVS3; T7 - PVS3 modified; T8 - PVS2 + 1% phloroglucinol. After 15 days of immersion of seeds in LN, the cryotubes were removed and rapidly reheated to a temperature of 40 °C water bath for 1.5 minutes. Then, the seeds were washed with wash solution for 20 min. Later they were submitted to the germination te
