Organic Facility Information

Total GFS manufacturing capacity exceeds 100,000 liters for the combined production of specialty chemicals. GFS is ISO-9001:2000 certified.
 
Manufacturing
The heart of our organic chemical manufacturing is a 14,000 square foot, indoor, state-of-the-art product facility in Columbus, Ohio - open since 2000. This new chemical plant demonstrates GFS Chemicals' investment to specialty organic chemicals.
Types of Chemistry
We can perform these types of chemistries: acetylenes and olefins; halogenation/dehydrohalogenation; Grignard,  alkylation; amination; bromination, chlorination, Birch reductions, esterification; epoxidation; Skraup quinoline syntheses; and low pressure hydrogenation.
 
Batch Unit Operations
Batch unit operations include: batch reactions; non-reactive mixing; extraction; filtration; centrifugation; crystallization and drying (tray and rotary vacuum); distillation and stripping; and sublimation (kilo lab scale).
 
 
Bulk Chemical Handling
We are capable of handling these bulk chemicals: anhydrous liquid ammonia; destabilized acetylene; sodium/lithium and corresponding amides; bromine; iodine; ethylene oxide; thionyl chloride; sulfuryl chloride; chlorosulfonic acid; hydrogen sulfide; sodium cyanide; liquid nitrogen; carbon disulfide trimethylchlorosilane and organosilanes.  
 
 
Manufacturing Equipment
"Kilo" Laboratory: Glassware up to 50 liters. Processing is carried out in walk-in lab hoods and bench top hoods. Distillation columns from 1” x 1' to 2.5” x 6'.
 
Production Plant Reactors & Capacities

Miscellaneous Manufacturing Information
Handling capacity. We are able to handle: liquefied gases, refrigerants, and reactive materials such as acetylene and propargyl compounds, olefins, ethylene oxide, silanes, and most solvents including carbon disulfide.   
 
Product separation and purification techniques.  Includes custom- built distillation systems, as well as thin film and rotary evaporators. Various centrifuge and drying stations are equipped for the bulk handling of a wide range of organic intermediates and salts of organic acids.

Purity profiles. For both raw materials and finished goods are maintained through advanced analytical instrumentation that includes GCMass Spectrometry and HPLC.
