F. Haber s catalytic synthesis of NH3 developed in collaboration with C. Bosch into a large-scale industrial process by 1913. (Hater was awarded the 1918 Nobel Prize in Chemistry for the synthesis of ammonia from its elements Bosch shared the 1931 Nobel Prize for contributions to the invention and development of chemical high-pressure methods , the Hater synthesis of NH3 being the first high-pressure industrial process.)... 

COMPARISON OP REPRESENTATIVE METHODS FOR THE CONCENTRATION OF TRACE ORGANIC COMPOUNDS IN HATER... 

Freeze Conceit tret ion Hater sample is partially frozen, concentrating the dissolved substances in the unfrozen portion. All sample types Minimizes sample losses due to volatilization or chemical modification. Principal losses occur due to occlusion, adsorption, evaporation and channelling in the ice layer. Limited sample size. 

Lyophillzation Hater sample is frozen and pure water is removed by sublimation under vacuum. Nonvolatile organics Can handle large sample volumes. Selective loss of volatile organics. Inorganic constituents concentrated simultaneously. 

Vacuum Distillation Hater is evaporated at reduced pressure and at or near ambient temperature. Nonvolatile organics Slow process when sample volumes are large. Inorganics also concentrated. Sample contamination is low but sample may be modified due to thermal degradation or chemical and microbial reactions. 

Reverse Osmosis Hater is forced through a membrane by application of pressure thereby enriching the water sample in constituents which ordinarily cannot pass through the membrane. Molecular weight > 200 Compounds of small size are not concentrated. Inorganic materials may contaminate sample. Membranes may either adsorb constituents or release impurities into the sample. 

Surface Adsorption Hater sample is passed through a column of the adsorbent and the adsorbed organic constituents subsequently eluted with a smaller volume of organic solvent. All sample types Adsorbents Include charcoal, macroretlcular resins, polyurethane foams, bonded phases and ion-exchangers. Generally have high capacity but sample discrimination may be a -problem. Sample modification and Incomplete recovery are further possible problems.

Molecular weights of the copolymers were determined by gel permeation chromatography (GPC) with four p-styragel (Haters) columns calibrated using polystyrene standards. Chloroform was used as the eluate at a flow rate 1.5 ml/min. An LKB-2140 Ultraviolet Photodiode Array detector was used to detect the polymer with a scan range from 190 to 370 nm.

A gas-oil-water mixture was introducec into a windowed cell which could be agitated, cooled or heated. Hater was maintained at some 251 weight in the mixture. Tests were concucted at normal (360 scf/bbl) and high (3000 scf/bbl) GOR.
