Pure benzophenone melts at 48-49 deg. The purpose of the fee is to recover costs associated Chim. ; Lee, T.D. It is a free radical photoinitiator, mainly used in free radical UV curing systems, such as coatings, inks, adhesives, etc. This could cause the freezing point to be different in different parts of the solution. the Ecol., 33, 2005, 17-26. umn class: Standard polar; Column type: Capillary; Start T: 180 C; CAS no: 119619; Active phase: Carbowax 20M; Phase thickness: 0.08 um; Data type: Kovats RI; Authors: Tudor, E.; Moldovan, D.; Zarna, N., Temperature dependence of the retention index for perfumery compounds on two carbowax-20M glass capillary columns with different film thickness. ; Trieschmann, H.G., Jaquerod, Adrien; Wassmer, Eugene, J.

No. Another possible explanation is that there might be a calibration error in the thermometer, causing it to read a lower temperature than the actual temperature. The product should be moisture-proof, sun-proof, and away from heat sources during storage and transportation, and its temperature should not exceed 45C. Acta, 1978, 23, 196-198. DeKruif, C.G. - 575. Pigment, medicine, perfume, insecticide intermediate, can also be used for UV curing resin, ink and coating photoinitiator. ; Lee, H.W. Eng.
