This π -conjugated system enables electronic excitation in the visible and near-ultraviolet regions. This is of particular interest for many applications, such as corrosion inhibition dye-sensitized solar cells (DSSC), organogels, and fluorescent probes for analytical testing. In addition, many hydrazine derivatives show notable biological and therapeutic activities such as the treatment of tuberculosis, Parkinson’s disease, and hypertension. Schiff bases form a remarkable class of ligands because of their unique properties, such as stability under different conditions, diversity of donor sites, the flexibility of synthesis, and formation of ranges in various coordination geometries in a wide range of complexes. Their complexes have received widespread attention due to their wide range of applications, such as catalysis, electrochemistry, biological sciences, optics, guest chemistry, and molecular recognition. Therefore, from theoretical and practical points of view, the synthesis of hydrazine derivatives is an important issue. In the present study, we describe a new, efficient, and environmentally benign synthetic method for the formation of hydrazine derivatives with heterogeneous catalysis starting from ketones.","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":"174 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75711596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the activation of caspase-3 and hence apoptosis induced by these molecules, was also explored.

Furfural is currently a commodity chemical, identified as one of the most promising chemical platforms directly derived from biomass, to produce chemicals, biofuels, and additives. Wood scraps are a good source of natural pentoses that contains up to 25%. Taking this into account, the goal of the research was to evaluate the recovery of furfural from wood scraps. The process of recovery of furfural was carried out by acid-catalyzed pentoses dehydration, associated with a hydrodistillation. As a catalyst, we used a solution of hydrochloric acid of 10% wt. The physicochemical analysis of the samples obtained allowed us to characterize and evaluate the recovery process. The results showed that under the experimental conditions evaluated, the degree of recovery of furfural was about 5%.","PeriodicalId":11441,"journal":{"name":"ECSOC-25","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80219257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
