Low cost selective sensor for carbonyl compounds in air based on a novel conductive poly(p-xylylene) derivative

LI, Rosamaria W. C.; CARVALHO, Lilian R. F.; VENTURA, Leonardo; GRUBER, Jonas (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 ...

Whisky, Whiskey and Bourbon: Composition and Analysis of Whisky

Universidade Estadual Paulista (UNESP) (2015-09-14)

Whisky has traditionally been assessed by expert blenders with many years of experience, by comparison of samples with experience or a reference. Vocabularies of descriptive terms have been used, which have often been ...

4-hydrazinobenzoic acid as a derivatizing agent for aldehyde analysis by HPLC-UV and CE-DAD

Universidade Federal de São Carlos (UFSCar); Universidade do Porto; Universidade de São Paulo (USP); Universidade Estadual Paulista (Unesp) (2018-09-01)

Aldehydes are relevant analytes in a wide range of samples, in particular, food and beverages but also body fluids. Hydrazines can undergo nucleophilic addition with aldehydes or ketones giving origin to hydrazones (a group ...

Emission profiles of carbonyl compounds at a Brazilian charcoal plant

Anunciação, Daniela Santos; Sousa, Eliane Teixeira; Carvalho, Albertinho Barreto de; Pereira, Pedro Afonso de Paula; Anunciação, Daniela Santos; Sousa, Eliane Teixeira; Carvalho, Albertinho Barreto de; Pereira, Pedro Afonso de Paula (Brasil, 2012)

Brazilian steel industry consumes huge amounts of charcoal. The charcoal plants are responsible for atmospheric emissions of volatile organic compounds such as carbonyl compounds (CC). In this work, the profile and the ...

Determination of 11 Low-Molecular-Weight Carbonyl Compounds in Marine Algae by High-Performance Liquid Chromatography

Silva, Vilma Mota da; Veloso, Márcia Cristina da Cunha; Sousa, Eliane Teixeira; Santos, Gislaine Vieira dos; Accioly, Miguel da Costa; Pereira, Pedro Afonso de Paula; Andrade, Jailson Bittencourt de; Silva, Vilma Mota da; Veloso, Márcia Cristina da Cunha; Sousa, Eliane Teixeira; Santos, Gislaine Vieira dos; Accioly, Miguel da Costa; Pereira, Pedro Afonso de Paula; Andrade, Jailson Bittencourt de (2006)

A new analytical method is reported for the determination of 11 volatile carbonyl compounds isolated at room temperature from the headspace of marine algae. This method is based on the conversion of the carbonyl compounds ...
