Severe neurotoxicity associated with exposure to the solvent 1-bromopropane (n-propyl bromide
Albemarle Corporation (NYSE: ALB), a global developer, manufacturer and marketer of highly engineered specialty chemicals, is increasing global prices for its n-Propyl bromide
The solvent covered by ASTM D7553, n-propyl bromide
, has been approved by the US Environmental Protection Agency under its Significant New Alternatives Policy as an alternative to chlorofluorocarbons.
Protection of stratospheric ozone: listing of substitutes for ozone depleting substances; n-Propyl bromide
in solvent cleaning; final rule.
The compounds are hexachlorobutadiene (a solvent used to make vinyl chloride), n-propyl bromide
(a solvent that is used in pharmaceutical production), 6-bromo-2-methoxyl-napthalene (used to make the fumigant, methyl bromide) and halon-1202 (used in fire extinguishers).
Discounting methyl bromide and ethylene dibromide, whose use is being regulated out of existence, brominated hydrocarbons will enjoy above-average growth as TBBA increases its share of the flame retardants market and compounds such as n-propyl bromide
find growing use in such diverse applications as solvents, adhesives and electronics cleaning, often as a replacement for more environmentally suspect substances.
These include perchloroethylene (PERC) and methylene chloride (MECL)--classed as carcinogenic, mutagenic or reproductive toxins by the Solvent Emissions Directive 1999-13-EC--and n-Propyl Bromide
(nPB), a candidate under REACH as a 'Substance of Very High Concern' (SVHC).
[USPRwire, Sat Oct 27 2018] To produce pesticides, fragrances, flavors, pharmaceuticals, and the other chemicals, n-Propyl Bromide
Exercise caution when considering n-Propyl Bromide
(nPB), as the ACGIH (American Conference of Governmental Industrial Hygienists) now recommends a threshold limit value of just 0.1 ppm based on health hazards.
Substances which are already on the candidate list and proposed for inclusion into the Annex XIV like 1-brompropane (n-propyl bromide
) are not considered as suitable alternatives.
Electronic manufacturing services (EMS) companies looking to eliminate the need to use n-Propyl Bromide
(nPB) in the defluxing of their PCB boards and panels can call on leading industrial finishing equipment manufacturer Guyson International for an effective solution to their cleaning problems with the installation of a Kerry Microsolve Co-solvent cleaning system.
