Rotenone Residues on Olives and in Olive Oil

Journal of Agricultural and Food Chemistry, 2002
The disappearance of rotenone on olives under field conditions was studied. The field data showed that rotenone residues on olives decreased with a half-life (t(1/2)) of 4.0 days. After pre-harvest time (10 days) the residues were higher than the maximum residue level fixed in Italy (0.04 mg/kg). Experiments with model systems showed that the mechanism

Pesticide Residues in Olive Oil

1995
The attacks of pests and diseases and the presence of weeds make it necessary to apply pesticides to olive trees to ensure crop protection. Residues of these compounds may remain and contaminate the oil produced. For the analysis of pesticide residues in olive oil, the most common methods are multiresidue methods for fatty substrates, based on ...

The Demetallization of Residual Fuel Oil and Petroleum Residue

Petroleum Science and Technology, 2010
Abstract Heavy residual fractions were treated to remove metal contaminants by nonconventional methods, such as centrifugation, solvent extraction, and contacting the material with various chemicals and chelating agents. The centrifugal method was found to be effective in reducing water-soluble metal salts and the Na/V mass ratio was reduced from about

Pesticide Residues in Uruguayan Lemon Oils

Journal of Essential Oil Research, 1999
Abstract Organophosphorus and organochlorine residues were studied on 31 samples of Uruguayan lemon oils corresponding to the 1995 season from North and South areas of fruit production in the country. Organochlorine pesticides were absent in all die samples analyzed.

14C-dimethoate residues in olive oil during oil processing

Journal of Environmental Science and Health, Part B, 1999
An olive tree was treated twice in the field with 14C-dimethoate (237.7 muCi, 2.4 g) and 14C residues were determined in the olive fruits at harvest. The fruits were crushed and pressed to extract the crude oil, then refined by neutralization, bleaching and deodorization.

Residual Oil Zone: Paleo Oil Characterization and Fundamental Analysis

SPE Improved Oil Recovery Conference, 2016
Abstract In most reservoirs around the world, paleo oil exists below the free water level and is considered residual oil to natural/geological waterflood. This non-trivial resource of residual oil will not flow by primary or secondary recovery means but requires carefully designed enhance oil recovery (EOR) methods to mobilize it.

Acephate and buprofezin residues in olives and olive oil

Food Additives and Contaminants, 2000
Field trials were carried out to study the persistence of acephate and buprofezin on olives. Two cultivars, pizz'e carroga and pendolino, with very large and small fruits respectively were used. After treatment, no difference was found between the two pesticide deposits on the olives.

Mechanochemical processing of oil residues

Chemistry and Technology of Fuels and Oils, 2012
The feasibility of processing heavy-oil resid by mechanochemical action is explored. It is shown that hydrocarbon destruction and condensation processes occur in equal measure. The n-paraffins C6-C16 are subject to destruction, and the condensation processes are associated with alkylation of aromatic hydrocarbons by paraffin-destruction products.

Oil-Seed-Residue Glues

Journal of Fluids Engineering, 1932
Abstract The paper describes the history, characteristics, uses, and limitations of soya-bean glue, or generically of seed-residue glue. This is the newcomer in the glue field, its use practically dating from 1923. The adhesive base of the seed-residue glues is the cake or meal resulting from the oil-pressing of soya beans, peanuts ...

ELECTRIC CONDUCTIVITY OF RESIDUAL OILS

Liquid Fuels Technology, 1984
There are few reports available detailing the electrical conductivity of heavy residual oils. The development of a model for the conductivity can lead to an increased understanding of the fundamental properties of such oils, and furthermore, conductivity is an important parameter for certain processing sequences.
