Preparation and characterization of tetrasubstituted zinc(II) phthalocyanines in which sulfur is not linked to the macrocycle are reported herein for the first time. Thioacetic acid S-[3-(3,4-dicyano-phenoxy)-propyl]ester ...
Produção de biodiesel em um reator de micro-ondas utilizando catálise homogênea e heterogênea, e o desenvolvimento de modelos quimiométricos para quantificação
(Universidade Federal de Minas GeraisUFMG, 2015-02-25)
In this study, it the feasibility of production of biodiesel in a microwave-assisted reactor was verified. The transesterification reaction was carried out using soybean oil and methanol as esterifying agent. Homogeneous ...
Diseño de un sistema de producción de biodiesel a partir de aceite del higuerilla
(Escuela Superior Politécnica de Chimborazo, 2013-07-18)
A production system was designed to obtain biodiesel from higuerilla oil, a vegetable oil that represents a viable alternative for the production of biodiesel, without competing with the food industry. We found influential ...
A new synthetic methodology for pyridinic sucrose esters and their antibacterial effects against Gram-positive and Gram-negative strains
(2020-03-01)
Described are the development of a new synthetic method using ultrasonic irradiation and sodium methoxide as catalyst for a series of pyridinic sucrose esters (py-SEs), derived from transesterification of sucrose with ...
Catalyst consumption during one and two steps transesterification of crude soybean oils
(Elsevier, 2013-12)
In this work, the transesterification reaction of refined and crude oils was studied. The reaction was carried out using methanol, with the aim of studying the effect of different catalysts, such as sodium and potassium ...
Síntese e avaliação de sílica tipo M41S contendo cátions CTA em transesterificação catalítica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2010-08-13)
The investments in the biofuel production have increased a lot in the last years mainly because of smaller damages they cause to the environment in comparison with the derived conventional petroleum fuels. The reaction of ...

(AMER CHEMICAL SOCWASHINGTON, 2012)
trans-Free interesterified fat was produced for possible usage as a margarine. Palm stearin, coconut oil, and canola oil were used as substrates for chemical interesterification. The main aim of the present study was to ...
EFFECT OF CHEMICAL INTERESTERIFICATION ON PHYSICOCHEMICAL PROPERTIES AND INDUSTRIAL APPLICATIONS OF CANOLA OIL AND FULLY HYDROGENATED COTTONSEED OIL BLENDS
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Blends of canola oil (CO) and fully hydrogenated cottonseed oil (FHCSO), with 20, 25, 30, 35 and 40% FHCSO (w/w) were interesterified under the following conditions: 0.4% sodium methoxide, 500 rpm stirring, 100C, 20 min. ...
Structured lipids obtained by chemical interesterification of olive oil and palm stearin
(ELSEVIER SCIENCE BV, 2010)
Interesterification of palm stearin (PS) with liquid vegetable oils could yield a good solid fat stock that may impart desirable physical properties, because PS is a useful source of vegetable hard fat, providing beta` ...
