Selective high performance liquid chromatography imprinted-stationary phases for the screening of phenylurea herbicides in vegetable samples

open access: yes, 2005
Molecularly imprinted polymers (MIPs) for the determination of phenylurea herbicides have been synthesized by polymerisation of the appropriated reagents mixture within the pores of preformed spherical silica particles leading to a silica-MIP composite ...

Solid-state NMR studies of inclusion compounds [PDF]

open access: yes, 1997
The work contained within this thesis is a study of inclusion compounds using solid-state NMR. Such compounds typically exhibit static and/or dynamic disorder, which precludes the use of diffraction-based techniques to obtain detailed structural ...

Evaluation of new selective molecularly imprinted polymers prepared by precipitation polymerisation for the extraction of phenylurea herbicides

open access: yes, 2005
Three different molecularly imprinted polymers (MIPs) have been prepared by precipitation polymerisation using linuron (LIN) or isoproturon (IPN) (phenylurea herbicides) as templates and methacrylic acid (MAA) or trifluormethacrylic acid (TFMAA) as ...

Free radical reaction of fluorine containing compounds [PDF]

open access: yes, 1989
This thesis is concerned with the free-radical addition of oxygen containing compounds of the adducts produced. Free-radical additions of ether compounds to fluoroalkenes have been done by previous workers and the chemistry of some of these adducts has ...

SINTESIS SENYAWA TURUNAN N-BENZOIL-N’- FENILUREA DAN HUBUNGAN KUANTITATIF STRUKTURAKTIVITAS SITOTOKSIK TERHADAP SEL HELA [PDF]

open access: yes, 2018
According to some research, urea has a pharmacophore for cytotoxic activity, so four analogs of N-benzoyl-N’-phenylurea (i.e N-benzoyl-N’- phenylurea; N-(4-methylbenzoyl)-N’-phenylurea; N-(4-methoxybenzoyl)-N’- phenylurea; N-(4-tertiary-butylbenzoyl ...

Cytokinin-like effect of a new phenylurea derivative.

open access: yes, 2001
We have synthesized 14 N-phenylurea derivatives, differing in the heterocyclic portion linked in N-position, and tested their cytokinin-like activity.

On the volatile flavour compounds of cooked trassi, a cured shrimp paste condiment of the Far East [PDF]

open access: yes, 1972
The volatile compounds of cooked trassi, a cured shrimp paste condiment of the Far East have been studied. The techniques of volatiles isolation, concentration, fractionation as well as methods of identification have been described.
