Re: HyperSolv -Reply



Hypersolv is the trade name (for Great Lakes Chemical Co.) for normal propyl
bromide [n-PB]  a solvent which has essentially the same distillation and
solvent properties as does 1,1,1 Trichloroethane.  Albemarle Corporation
produces the same product under the trade name Abzol.  This new choice in
cleaning solvents allows you to avoid the
expense of compliance with  NESHAP. 

The EPA has communicated that they intend to propose SNAP approval of n-PB.
 This will be done within the next few months.  There will be two conditions
of use: (1) 100 ppm exposure limit,
and (2) protective equipment required to avoid skin contact.  

Two US manufacturers are Great Lakes Chemical (West Lafayette, IN) and
Albemarle Chemical (Baton Rouge, LA).  Contact  numbers are as follows:

Great Lakes Chemical Co (GLCC):  (317) 497-6100
Albemarle Corp:  (504) 388-7040
