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.
3-Hydroxybenzaldehyde(cas: 100-83-4) can be used as a reactant along with ethyl acetoacetate and thiourea in the synthesis of corresponding dihydropyrimidine-2-thione (monastrol), using Yb(OTf)3 as a catalyst by Biginelli cyclocondensation reaction.Name: 3-Hydroxybenzaldehyde
