Treatment with organic solvents
for the delignification of rice husk was optimized by varying the concentration of solvents, changing the temperature, duration of the treatment and by adding or removing the catalyst.
Figure 6 shows the retention time of enolase on the Zorbax 300SB-Diphenyl stationary phase with acetonitrile as the organic solvent
The temperature has no significant effect on the extraction efficiency of the benzaldehyde, because of the contact surface between organic solvent
and the sample is very large and there is no limiting effect caused by slow mass transfer.
Industrial hygienists assessed the levels of workplace exposure to organic solvents
in 5000 women from across the US, from one month before conception through to the first three months of pregnancy (first trimester).
The secondary structures of the Eri SF treated with different organic solvents
were analyzed using ATR-IR.
However, activities of organic solvent
tolerant lipase and cyclodextrin glucanotransferase from P aeruginosa LST-03 (10) and P illinoisensis (9) respectively, were slightly inhibited by cyclohexane.
These results suggest that maternal occupational exposure to organic solvents
during pregnancy may have subtle adverse effects on fetal neurodevelopment in exposed children (Arch.
Regulations differ worldwide, importantly for coatings technology development, in their treatment of the various types of organic solvent
Key statement: Methods are provided for making solution masterbatches containing a diene elastomer in an organic solvent
and a silica filler, having a first average particle size, that is ground in an organic solvent
to form a silica having a reduced second average particle size.
Multiple adsorbents are placed in a centrifuge tube, along with organic solvent
and the extracted residues.
The team next immersed the balls in an organic solvent
containing luminescent chemicals.
