NOMENCLATURE HFC = Hydrofluorocarbon HPLC = High Performance Liquid Chromatography IC = Ion Chomatography ICP = Inductively Coupled Plasma PAG = Polyalkylene Glycol POE = Polyolester TAN = Total Acid Number
TOA = Total Organic Acid
The reagents used to determine the peroxide and acid numbers
were procured from (Penta, Czech Republic).
For both WRSSB6 and WRSBO, coatings formulated with resins having an acid number
of 40 gave a slightly lower [T.
The divalent calcium will only cause a noticeable problem with polymers that have a significant acid number
, and in rather apolar offset ink media, the calcium will not be charged as it is in aqueous media (and therefore will not be able to interact with whatever minimal acidity does exist on the grind resin).
Also, existing corrosivity indexes such as the total acid number
are insufficient indicators of a crude stock's real potential to corrode the storage tanks, pipelines and refining equipment that contain, transport and process it.
Standard Test Methods for Acid Number
1:1, respectively, in the presence of an acid catalyst at elevated temperature, wherein said mixture comprises monostyrenated-p-cresol, distyrenated-p-cresol, and tristyrenated-p-cresol and exhibits an acid number
of less than 0.
Generally, higher acid number
resins with higher levels of substitution do better in these tests (resins 4,5, and 6).
The acid number
of functionalized triglycerides was determined following ASTM D974-95.
Albemarle's ETHANOX biodiesel antioxidants can help producers control critical parameters of their fuels, such as oxidative stability (EN 14112), acid number
and peroxide content, as well as decrease gum formation.
There are two issues of industrial significance which are usually monitored in a polyester synthesis: acid number
and the refractive index of the distillate.
When a new synthetic lubricant is installed, the total acid number
(TAN) will be 0.
A unique combination of properties is exhibited by this resin, including neutral pH, high water solubility, low molecular weight and high acid number
featured new and reportedly user-friendly software for its NIR polyol analyzer system used to measure the hydroxyl value and acid number
of urethane polyols both in the lab and for on-line process control.
The Total Acid Number
, the Cold Soak Filterability particulate count and KF Water concentration are the lowest values ever reported for a B100 sample tested at CytoCulture.
