Translation of "Stickstoffbegasung" in English

A uniform solution is obtained with nitrogen gassing.

Then the excess digested sludge was rinsed out with waste water with nitrogen-fumigation.

The reaction mixture is stirred and purged with nitrogen at room temperature for 4 hours.

Filling is preferably performed in nitrogen atmosphere. Example 2

Basic additive and blanketing with nitrogen produce a synergistic effects.

The reaction mixture was then stirred at room temperature under nitrogen gasification for about 12 hours.

It is preferred to draw off the solutions into ampoules under aseptic conditions as well as under sterile gassing with nitrogen.

After the oxidation inhibitor is added under nitrogen, it is homogenized for 3 minutes and the mixture is then granulated.

The reaction mixture is stirred at room temperature for 15 h while gassing with nitrogen and with the exclusion of light and moisture.

According to the working examples, the copolyamides are prepared in the melt in a pressure autoclave with nitrogen sparging.

The solubilizate was filtered through a 0.45 ?m filter and packed under nitrogen in vials with rubber stoppers.

In addition, a 0.5% aqueous N-0923 solution (preparation III) was autoclaved in a nitrogen atmosphere.

The effect of nitrogen blanketing in addition to the vacuum applied is greater in the presence of a basic additive.

The solution was sterilized by filtration through a 0.22 ?m filter and dispensed under nitrogen into 1 ml ampoules.

The foregoing nitrile mixture (72.5 g) is heated at 200° C. (bath temperature) for 6.5 hours while gassing with nitrogen with a hot solution of 35.1 g of potassium hydroxide in 355 ml of diethyleneglycol.

The mixture is stirred for 1 hour at 25° C. while gassing with nitrogen and excluding light, resinous material separating out.

The solution is stirred for 11/2 hours at 20°-25° C. while gassing with nitrogen and thereafter a small amount of separated, red selenium is filtered off.

The mixture was warmed to a constant temperature of 55° C. and then electrolyzed at a cathode potential of -1600 mV (against SCE) while stirring and gassing with nitrogen, an amperage of 250 mA setting in.

The mixture was warmed to a constant temperature of 65° C. and then electrolyzed at a cathode potential of -1900 mV (against SCE) while stirring and gassing with nitrogen, an amperage of 160 mA setting in.

EXAMPLE 48 To 1440 ml of anhydrous tert-amyl alcohol are added, under nitrogen, 82.8 g of sodium and 1.2 g of anhydrous sodium bis-2-ethylhexyl sulfosuccinate as emulsifier.

The mixture was subsequently boiled at reflux for 95 minutes in an oil-bath (245° C.) while stirring and gassing with nitrogen, then left to cool to room temperature, rinsing into a round flask with 50 ml of toluene and steam-distilled for 75 minutes.

After addition of 0.1N hydrochloric acid to pH 5.8, the solution is poured over a Millipore Filter (0.2 micron) and put into a Multivial under nitrogen gassing.

The esterification components listed in Table I were weighed together into a stirred flask surmounted by a descending distillation column and were esterified under nitrogen at 220° C. until the characteristic data indicated had been reached.

In a 2 1 glass reactor equipped with a stirrer, a thermometer, a nitrogen inlet tube, a condenser and four feed vessels, the amounts (moles) of monomer c) stated in Table 3, in 100 ml of water, are initially taken and are heated with stirring and blanketing with nitrogen.

A sodium methylate solution freshly prepared from 50 ml of methanol and 2.6 g of sodium was treated while gassing with nitrogen with 15 g of 4-bromobenzamidine hydrochloride and 13.5 g of 1,3-bis(dimethylamino)-2-ethoxytrimethinium perchlorate (Cell.

Under aseptic conditions, it is now sterile filtered over a membrane filter of 0.22 ?m. pore width and filled in 40 ml. amounts into 100 ml. injection bottles with nitrogen gassing.

A solution of 28.5 g of tetrabromomethane in 519 ml of methylene chloride was treated dropwise while gassing with nitrogen at -15° C. within 13 minutes with a solution of 45.7 g of triphenylphosphine in 97 ml of methylene chloride.

The reaction mixture was transferred into a dropping funnel and then added dropwise at 0° C. and while gassing with nitrogen to a solution of 0.9 g of 3E-[trans-4-(trans-4-[1E-propenyl]cyclohexyl)cyclohexyl]-allyl pivalate, 0.03 g of copper-(I) chloride and 25 ml of absolute diethyl ether.
