Lubricants antioxidants

SiHcon tetrabromide [7789-66A], SiBr, and tribromosilane [7789-57-3], SiHBr, are used in a process to make high purity siHcon (40). Stannous bromide [10031 -24-0], SnBr2, is claimed as a catalyst in preparing a lubricant antioxidant (41). Stannic bromide [7789-67-5], SnBr, is used in the metallurgical separation of minerals (42). 

Processing aids cover chemicals used for specific purposes to assist processing. Some are identical to those included under additives, e.g. lubricants, antioxidants, mould release agents. The last of these may be regularly sprayed onto moulds and may occasionally lead to poor label adhesion or oil-like contaminants.

GC combined with different extraction and detection techniques, such as Py-GC, Py-GC/MS, SFE-GC, thermodesorption cooled injection system (TD-CIS)-GC/MS among others, has been widely applied to the analysis of many additives. The use of Py-GC and Py-GC/MS in the determination of lubricants, antioxidants, plasticizers, and flame retardants was discussed in depth by Wang and CO workers. In the case of antioxidants, Py-GC... 

Albemarle s combined net sales rose from US 941 M in 2000 to US 1110 M in 2003, despite very difficult trading conditions. Net income fell in the same period from US 102 M to US 72 M, and long-term debt rose from US 97 M to US 228 M These figures are partly explained by the fact that several acquisitions have been made. They included Akzo Nobel s refinery catalysts, the Korean distributor Taerim, Arkema s fine chemicals bromine business, Rhodia s phosphorus based flame retardants business for polyurethanes, the fuel and lubricant antioxidants business of Ethyl, the fine chemicals business of ChemEirst, and Martinswerk. 

This baseline correction technique can obviously be applied to the determination of styrene monomer in PS only if any other UV absorbing constituents in the polymer extract (e.g., lubricant, antioxidants) absorb linearly in the wavelength range 288-300 nm. If the polymer extract contains polymer constituents other than styrene with non-linear absorptions in this region, then incorrect styrene monomer contents will be obtained. An obvious technique for removing such non-volatile UV absorbing compounds is by distillation of the extract followed by UV spectroscopic analysis of the distillate for styrene monomer as described next.
