The object of this study is a technology of the new surface-active substances (SAS) based on sulfomethylated phenol. The study's aim was to improve the technology by a catalytic method, implying the development of industrial schemes for the synthesis proc... see more

The object of research is the reaction of phenol sulfomethylation in an aqueous medium, with the aim of obtaining water-soluble non-toxic products based on it used as surfactants. One of the most problematic places is the need to maintain the stability of... see more

A recovery study of phenol with Polymer Inclusion Membranes (PIMs) needs to be evaluated to determine values of transport kinetic parameter, level of stability, and selectivity of the membrane. This paper describes results of the evaluation of phenol tran... see more

Phenol is categorized as a refractory pollutant and its presence in water stream is strictly limited according to the government regulation. The present study investigated the degra-dation of phenol in aqueous solution by the effect of ultrasound. The pro... see more

Petunia hybrid Vilm. is an ornamental plant that has the potential to be developed because its flowering period does not know the season and comes with various motifs and flower colors that can add cultivation and commercial value. Information on the morp... see more

 Phenolic compounds are used in human diet, commonly present in plants. Foremost polyphenolic compounds found in plants are flavanols, flavonoids, flavonones, iso-flavones, phenolic acids, flavonoids, chalcones, lignans etc. These compounds possess a... see more
