Isoamyl acetate preparation from reaction of vinyl acetate and Isoamyl alcohol catalyzed by H-ZSM-5 zeolite: a kinetic study
(Elsevier Science, 2018-06)
Microporous H-ZSM-5 zeolite having good crystallinity and with the presence of Brønsted acid sites exclusively, was prepared by hydrothermal treatment of Expanded Perlite. The as-prepared H-ZSM-5 was used as heterogeneous ...
Screening of dietary ingredients against the honey bee parasite Nosema ceranae
(MDPI, 2021-09-01)
Nosema ceranae is a major pathogen in the beekeeping sector, responsible for nosemosis. This disease is hard to manage since its symptomatology is masked until a strong collapse of the colony population occurs. Conversely, ...
Lactic acid as potential substitute of acetic acid for dissolution of chitosan: preharvest application to Butterhead lettuce
(Association of Food Scientists and Technologists of India, 2017-03)
Chitosan must be dissolved in acid solution to activate its antimicrobial properties. The objectives of present study were to determine whether acetic and lactic acids used to dissolve chitosan would influence its effectiveness ...

The aim of this research was to analyse the global indole-3-acetic acid (IAA) metabolism in three commercially used strains of Azospirillum brasilense. Methods and Results: Azospirillum brasilense Sp245, Az39 and Cd, ...
Synthesis of ε-oxo acids by photostimulated reactions of 2-(2-iodophenyl)acetate ion with carbanions by the SRN1 mechanism. Synthesis of novel 3-benzazepin-2-ones
(Arkat, 2011-05-09)
The synthesis of 3-benzazepin-2-ones using commercially available 2-(2-iodophenyl)acetic acid as starting material is described. The synthetic strategy involves the SRN1 substitution reaction in DMSO as solvent under ...
Herbicidal effects of n-hexane, ethyl acetate and methanol extracts of billygoat weed (Ageratum conyzoides l.) leaveson amaranthus spinosus l. growth
(Allelopathy Journal, 2021-11)
The herbicidal activity of Ageratum conyzoides L. extracts was evaluated on the weed Amaranthus spinosus L. The leaves of A. conyzoides were sequentially extracted with n-hexane, ethyl acetate and methanol. In pot culture, ...
