Special Issue: "Organic Reactions in Green Solvents".
To overcome the well-established drawbacks of conventional organic solvents (toxicity, non-biodegradability, flammability, accumulation in the atmosphere) remarkable research efforts have been recently devoted to the replacement of traditional organic reaction media by the so-called Green Solvents. In this sense, the choice of a safe, non-toxic, biorenewable and cheap reaction media is a crucia...
متن کاملFactors Involved in the Use of Organic Solvents as Precipitating and Drying Agents of Immune Sera
1. In concentrations of 70 to 75 per cent the organic solvents methyl, ethyl, and propyl alcohols, and acetone cause complete precipitation of serum proteins and produce maximum loss in solubility. We have referred to this concentration range as the critical concentration. 2. As the concentration of the solvents is increased from about 75 per cent precipitation continues complete but loss in so...
متن کاملHybrid Assembly Cleaning with Non-Halogenated Solvents
Because of xegulatoe, economic and community pressures, halogenated solvents, routinely used for various cleaning operations in the electronics industry, are being aggressively phased out. A fundamental undemanding of the chemical n a t u ~ of process specific contamination is essential to enable thegroper selection of appropriate alternative cleaning agents. In this study, the role and need of...
متن کاملExposure to Organic Solvents Used in Dry Cleaning Reduces Low and High Level Visual Function
PURPOSE To investigate whether exposure to occupational levels of organic solvents in the dry cleaning industry is associated with neurotoxic symptoms and visual deficits in the perception of basic visual features such as luminance contrast and colour, higher level processing of global motion and form (Experiment 1), and cognitive function as measured in a visual search task (Experiment 2). M...
متن کاملCleaning agents and asthma.
Although cleaners represent a significant part of the working population worldwide, they remain a relatively understudied occupational group. Epidemiological studies have shown an association between cleaning work and asthma, but the risk factors are uncertain. Cleaning workers are exposed to a large variety of cleaning products containing both irritants and sensitizers, as well as to common in...
