Dichloromethane abatement

30 07 1991Dichloromethane upon reacting with glycolates may form cyclic ethers by ring closure through the --CH 2-- group or it may react with two glycolate molecules and generate a higher molecular weight glycolate In the latter reaction it is capable of further reaction with dichloromethane At this time it can close the ring or generate a higher molecular weight glycolate

Dichloromethane

Dichloromethane (DCM mol wt 93 328) was first prepared in 1840 by mixing chloromethane and chlorine and exposed to sunshine It has been used as a versatile solvent to dissolve various organic compounds in many chemical processes since World War II Currently dichloromethane is manufactured by two sets of processes hydrochlorination of methanol and direct chlorination of methane

Effect of molecular weight on the properties and organic

The molecular weight dependent polymer properties were studied and compared Photo-voltaic applications of the polymers in bulk heterojunction (BHJ) solar cells revealed that the power con- version efficiency increased significantly (from 0 9% to 4 1%) as the M n increased from 10 kg mol−1 to 73 kg mol−1 while further increase of the molecular weight had less influence on the solar cell

Solvent extractives of wood and pulp (Proposed revision of

In general dichloromethane extraction gives lower amounts of extractives than either acetone or ethanol/benzene Extraction with 1/3 ethanol and 2/3 benzene typically gives the highest level of extractives due to the additional dissolution of low molecular weight carbohydrates and polyphenols These generalizations do not apply to all wood species in cluding some tropical hardwoods

High molecular weight HALS in LPDE

The amount of high molecular weight hindered amine light stabilizer (HALS) in low density polyethylene (LDPE) was determined using two pretreatment methods Soxhlet extraction and pressurized solvent extraction (PSE) The recoveries of high molecular weight HALS obtained by the two methods were compared It became apparent that PSE is capable of obtaining much higher recovery rates of high
