1,2-Dichloropropane is an intermediate in the production of perchloroethylene and other chlorinated chemicals. [4] It was once used as a soil fumigant , chemical intermediate, as well as an industrial solvent and was found in paint strippers, varnishes, and furniture finish removers but some of these uses have been discontinued.
If the test result is expected to be below 0.10% (by mass), prior to performing the test, the sample can be distilled to produce a 10% (by volume) bottoms. [ 1 ] [ 2 ] If the sample contains ash -forming constituents and/or non-volatile additives, these will add to the carbon residue value, and be included as part of the total reported carbon ...
ClC 2 H 4 Cl + 5 / 2 O 2 → 2 CO 2 + H 2 O + 2 HCl It is also toxic (especially by inhalation due to its high vapour pressure ) and possibly carcinogenic . Its high solubility and 50-year half-life in anoxic aquifers make it a perennial pollutant and health risk that is very expensive to treat conventionally, requiring a method of ...
Nominally 1 cm square copper coupon prepared per ASTM B810-01a(2017) Cleaning Method I. Mixed flowing gas (MFG) is a type of laboratory environmental testing for products, particularly electronics, to evaluate resistance to corrosion due to gases in the atmosphere. Mixed Flowing Gas (MFG) test is a laboratory test in which the temperature (°C ...
Chiral recognition implies the ability of chiral stationery phases to interact differently with mirror-image molecules, leading to their separation. The mechanism of enantiomeric resolution using CSPs is generally attributed to the “three-point" interaction model (fig.1.) between the analyte and the chiral selector in the stationary phase.

Supercritical fluid chromatography (SFC) [1] is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. [2] [3] It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds.
Quantitatively, the test measures the amount of carbonaceous residue remaining after the oil's evaporation and pyrolysis. [ 1 ] [ 2 ] [ 3 ] In general, the test is applicable to petroleum products which are relatively non-volatile, and which decompose on distillation at atmospheric pressure. [ 4 ]
