Replacement of Hazardous Chemicals the Case of DMC

Oligomer Phosphorus Reaction Isocyanate

Dimethyl carbonate DMC is a versatile compound that is an attractive alternative to phosgene 68, 69 and which could be synthesized in a eco-friendly process by catalytic oxidative carbonylation of methanol with oxygen Enichem, Italy 70 and Figure 1.9 Bhopal and alternative routes to N-methyl 2-naphthyl carbamate 67 . UBE, Japan 71 processes . DMC can act as a substitute for phosgene and toxic methylating agents like dimethyl sulfate and methyl chloride, and can also find use as a safe solvent...

Ecofining New Process for Green Diesel Production from Vegetable

Calendrier Remplir

Franco Baldiraghi, Marco Di Stanislao, Giovanni Faraci, Carlo Perego, Terry Marker, Chris Gosling, Peter Kokayeff, Tom Kalnes, and Rich Marinangeli Existing technology for producing diesel fuel from vegetable oil has largely centered on the production of FAME biodiesel 1-3 . While FAME has many desirable qualities, such as high cetane, there are other issues associated with its use such as poor stability and high solvency, leading to filter plugging problems. Moreover, there has been little...

Towards the Direct Oxidation of Benzene to Phenol

Phenol Process

Marco Ricci, Daniele Bianchi, and Rossella Bortolo 13.1 Phenol is one of the most important intermediates of the chemical industry. Its current global capacity is put at about 8 x 1061 yr_1 and is forecast to grow near 4.5 per year through to 2009. The main consumption of phenol, accounting for nearly 40 of its global demand, occurs in the synthesis of bisphenol A (mainly used to produce polycarbonate for compact discs). This is followed by phenol use in the production of epoxy resins (used,...
