It was found that nano-SiO2-H2SO4 was catalyzed the three-component cyclocondensation of aryl/heteroaryl aldehydes, hydroxylamine hydrochloride and β-ketoesters toward the synthesis of α,β-unsaturated isoxazol-5(4H)-ones under green conditions. The reaction yielded the corresponding heterocycles at room temperature in relatively shorter reaction times. It merits mentioning that the mild conditions allowed the synthesis of several α,β-unsaturated isoxazol-5(4H)-ones using this method. Some new derivatives of isoxazolones were also synthesized and characterized. It was efficient, clean, simple, safe and ecol. friendly. This straightforward method was cost-effective and required no preparation of reactants.

The author of 《New polymeric adsorbent materials used for removal of phenolic derivatives from wastewaters》 were Davidescu, Corneliu-Mircea; Ardelean, Radu; Popa, Adriana. And the article was published in Pure and Applied Chemistry in 2019. Name: 3-Hydroxybenzaldehyde The author mentioned the following in the article:

For the treatment of waste waters containing phenols or phenolic compounds several unconventional methods are applied, such as: inverse osmosis, coagulation, solvent extraction, flotation-coagulation combined processes, adsorption, and anaerobic processes. From all used remediation processes adsorption has a higher applicability degree due to its main advantages: simplicity, ease of use and operation and high efficiency. It is important to develop and use new adsorbents with higher regeneration degree and longer life time. Chem. modification of polymeric matrixes with pendant functional groups is a valuable method used to improve the surface and interface chem. of polymeric adsorbents, to achieve better adsorption performance and to design tailor-made adsorbents with respect to specific pollutants. In present study new adsorbent materials were obtained starting from chloromethylated styrene-divinylbenzene copolymers with different degrees of crosslinking (6.7%, 12% and resp. 15% DVB), functionalized by reaction with 3-hydroxibenzaldehyde. The polymeric intermediates were further modified by polymer-analogous reaction with iso-propylamine and diethylphosphite with the aim to improve their adsorptive properties. The obtained polymeric adsorbents were tested for remediation of waters containing phenol (P), 2,3-dimethylphenol (2,3-DMP) and 2,4,6-trimethyl-phenol (2,4,6-TMP). Based on obtained exptl. data the adsorption mechanism, process kinetics and thermodn. were studied.3-Hydroxybenzaldehyde(cas: 100-83-4Name: 3-Hydroxybenzaldehyde) was used in this study.

Due to increasing demands for ecofriendly processes within the framework of green chem., and having shown substantial properties, especially in terms of toxicity, biodegradability, cost, and ease of preparation under ambient conditions, deep eutectic solvents (DESs) have become a suitable candidate as green solvents for reaction media in the past decade.

Zhang, Jin; Guo, Cheng; Cai, Wensheng; Shao, Xueguang published an article in 2021. The article was titled 《Direct non-trilinear decomposition for analyzing high-dimensional data with imperfect trilinearity》, and you may find the article in Chemometrics and Intelligent Laboratory Systems.Recommanded Product: 3-Hydroxybenzaldehyde The information in the text is summarized as follows:

Trilinear decomposition has been employed in the anal. of three-way anal. data. However, it is difficult to keep a perfect trilinear structure for the data in real applications. A direct non-trilinear decomposition (DNTD) algorithm is proposed in this study for analyzing the three-way data with imperfect trilinearity caused by the shift or the variation of the chromatog. or spectral profiles in repeated measurements. In the method, two alternating steps are contained to resolve the constant and shifting profiles for each component, resp. The first step is based on a pseudo-trilinear decomposition, and the second step involves a slice-based matrix decomposition Furthermore, for reducing the ambiguity caused by the relaxation of trilinear constraint, an average profile regularization is introduced. Three datasets were used to validate the proposed method, including a simulated spectral dataset, a gas chromatog.-mass spectrometry (GC-MS) dataset and a flow injection anal. (FIA) dataset. Furthermore, a comparison with parallel factor anal. (PARAFAC), alternating trilinear decomposition (ATLD), PARAFAC2 and multivariate curve resolution-alternating least squares (MCR-ALS) was performed. The profiles with variant shifts were correctly extracted and a further understanding of the FIA dataset was obtained.
