Aqueous-Organic Biphasic Systems. Extraction of organic compounds
(Elsevier, 2020)
Liquid-liquid extraction (LLE) is a method of separation based on the distribution of a compound between two essentially immiscible solvents. Extraction procedures are carried out for two main reasons. An exhaustive ...
Active nickel-based reduction of organic compounds
(Springer, 2003-12)
The reducing system NiCl2·2H2O-Li-arene cat (cat is catalyst) was proposed for use to reduce a wide range of organic compounds, including alkenes, alkynes, carbonyl compounds, imines, halogenated derivatives, sulfonates, ...
Phosphorus sources associated with organic compound in broccoli production and soil chemical attributesFontes de fósforo associadas ao composto orgânico na produção de brócolis e atributos químicos do solo
(2019-04-01)
Phosphorus is a finite natural resource and the use of gradual-release phosphate sources, associated with an organic compound may favor a more rational use of this nutrient, since organic matter protects P from soil fixation. ...
Low cost selective sensor for carbonyl compounds in air based on a novel conductive poly(p-xylylene) derivative
(ELSEVIER SCIENCE BV, 2009)
A novel poly(p-xylylene), PPX, derivative bearing phenyl side groups was electrochemically synthesized in 85% yield. The polymer, poly(2-phenyl-p-xylylene) (PPPX), presented a major fraction (88%) soluble in common organic ...
SOLIDS COATED WITH SODIUM TETRACHLOROPALLADATE - SORBENTS FOR REDUCED SULFUR-COMPOUNDS IN AIR
(Gordon Breach Sci Publ Ltd, 2014)
Antioxidant compounds of organically and conventionally fertilized jambu (Acmella oleracea)
(2016-07-02)
Acmella oleracea (jambu), native to the Amazonas region (Brazil), has cosmetic and pharmacological properties, many of which are due to chemical components with antioxidant activity. Since organic cultivation has been ...
