a terpolymer was made, and then was used to adsorb metals via forming resin Structural verification of resin was achieved by employing instruments like 1HNMR, FTIR, and viscosity was examined to estimate the average molecular weight .
US agricultural chemical products maker Pace International LLC said it had purchased the agricultural product line and servicing division of water treatment firm CH2O
The appellant was the founder, president, and chairman of the board of CH2O
, a company that blends chemicals to create products such as acid cleaners.
"Most production managers don't really know what a sanitation crew is," says Henry Carsberg of CH2O
Eco Water, an Olympia, Wash.-based consulting and cleaning-chemical firm.
Another peak observed at m/z 203 (C11H7NO3) was due to the loss of isopropyl (C3H7) group of the side chain of fragmented ion C14H16NO3 (m/z 246), which on further loss of CH2O
yielded m/z 173 fragment ion corresponding to C10H5NO2.
HRMS of compound 1 showed molecular ion peak at m/z 442.381061 corresponds to molecular formula C30H50O2.EIMS showed intense peak at m/z 412 due to the loss of CH2O
, 124 due to the loss of C8H15 and loss of water other peak appearing in EIMS are explained in Figure 1 which showed the presence of steroidal skeleton.
