DESARROLLO Y CARACTERIZACION DE PELÍCULAS DE ALMIDÓN DE MAÍZ POR MEZCLADO CON COMPUESTOS MÁS HIDROFÓBICOS

Ortega Toro, Rodrigo (Universitat Politècnica de València, 2015-07-01)

[EN] Different strategies were used to improve physical properties of corn starch based films, with glycerol (30%) as plasticizer, based on increasing their hydrophobic character in order to reduce the materials' water ...
Efecto de la incorporación de tensoactivos en las propiedades físicas de films a base de almidón de maíz

Ortega Toro, Rodrigo (Universitat Politècnica de València, 2013-05-31)

[ES] El objetivo de este trabajo fue estudiar el efecto de la adición de tensoactivos sobre las propiedades mecánicas, ópticas y de barrera (al oxígeno y vapor de agua) de films a base de almidón de maíz y glicerol, para ...
Effect of organic species on the solar detoxification of water polluted with pesticides

Soler Escoda, Juan Miguel; Santos-Juanes Jordá, Lucas; Miró Martínez, Pau; Vicente Candela, Rafael; Arques Sanz, Antonio; Amat Payá, Ana María (Elsevier, 2011-04-15)

The effect of organic species on a solar-driven photo-Fenton treatment of a mixture of pesticides (methyl-oxydemethon, methidathion, carbaryl and dimethoate) has been studied in this paper. Triethoxyisododecyl alcohol, ...
Effect of the incorporation of surfactants on the physical properties of corn starch films

Ortega Toro, Rodrigo; Jiménez Marco, Alberto; Talens Oliag, Pau; Chiralt, A. (Elsevier, 2014-07)

[EN] The effect of surfactant addition on structural, mechanical, optical and barrier properties of corn starch-glycerol based films was studied. Sorbitan monopalmitate, monostearate or monooleate were incorporated into ...
Efficient production and separation of biodegradable surfactants from cellulose in 1-butyl-3-methylimidazolium chloride

Puga, Alberto V.; Corma Canós, Avelino (Wiley-VCH Verlag, 2014-12)

[EN] Alkyl glycoside biodegradable surfactants were produced from cellulose and 1-octanol or 1-dodecanol in a one-pot, two-step (hydrolysis-glycosidation) process in 1-butyl-3-methylimidazolium chloride. Both surfactant ...
From biomass to chemicals: Synthesis of precursors of biodegradable surfactants from 5-hydroxymethylfurfural

Arias Carrascal, Karen Sulay; S.I. AL-RESAYES; Climent Olmedo, María José; Corma Canós, Avelino; Iborra Chornet, Sara (Wiley-VCH Verlag GmbH&Co. KGaA, 2013-01)

The selective acetalization of 5-hydroxymethylfurfural (HMF) with long chain alkyl alcohols has been performed to obtain precursor of molecules with surfactants properties. If direct acetalization of HMF with n-octanol is ...
Inversion of selectivity in anion recognition with conformationally blocked calix[4]pyrroles

Gotor Candel, Raul Jesús; Costero Nieto, Ana María; Gil Grau, Salvador; Parra Álvarez, Margarita; Ochando Gómez, Luis Enrique; Chulvi, Katherine (Royal Society of Chemistry, 2012)

[EN] Two calixpyrrole derivatives were synthesised. A p-dimethylaminobenzoyl group was electronically attached to a pyrrole ring, establishing an intramolecular hydrogen bond in a 1,3-alternate conformation. The formation ...
New Oleic Acid-Capped Mesoporous Silica Particles as Surfactant-Responsive Delivery Systems

Poyatos-Racionero, Elisa; Pérez-Esteve, Édgar; Marcos Martínez, María Dolores; Barat Baviera, José Manuel; Martínez-Máñez, Ramón; Aznar, Elena; Bernardos Bau, Andrea (John Wiley & Sons, 2019-08-26)

[EN] A new delivery microdevice, based on hydrophobic oleic acid¿capped mesoporous silica particles and able to payload release in the presence of surfactants, has been developed. The oleic acid functionalization confers ...
One-Pot Synthesis of Biomass-Derived Surfactants by Reacting Hydroxymethylfurfural, Glycerol, and Fatty Alcohols on Solid Acid Catalysts

Garcia-Ortiz, Andrea; Arias Carrascal, Karen Sulay; Climent Olmedo, María José; Corma Canós, Avelino; Iborra Chornet, Sara (John Wiley & Sons, 2018)

[EN] A new type of biomass-derived non-ionic surfactants has been obtained by reacting hydroxymethylfurfural (HMF), glycerol, and fatty alcohols. For instance, 5-(octyloxymethyl)furfural glyceryl acetal can be obtained in ...
Preparación de surfactantes a partir de moléculas plataforma derivadas de la biomasa, en presencia de catalizadores heterogéneos

Stefanini, Laura (Universitat Politècnica de València, 2017-09-05)

Currently, surfactants (also called surface-active agent) are high production volume chemical compounds thanks to their wide range of applications, not only in the detergent industry, but also in other industrial sectors ...
Transformation of Cellulose into Biodegradable Alkyl Glycosides by Following Two Different Chemical Routes

Villandier, Nicolas; Corma Canós, Avelino (Wiley-VCH Verlag, 2011-04-18)

The transformation of cellulose into long-chain alkyl glycoside surfactants has been carried out following two different routes: (1) Direct transformation of cellulose to butyl-, hexyl-, octyl-, decyl- and dodecyl-a,ß-glycosides ...
