They are usually artificial peptides or proteins with amolar massof about 3 to 20 kDa. 通常它是人造的肽或者蛋白质,摩尔质量介于3至20kDa之间。 LASER-wikipedia2 Victor Meyer apparatus: In a demonstration in Cohen's Practical Organic Chemistry (1910) themolar massof diethyl ether was determined ...
19. Using L-lactic acid and glycolic acid as raw materials, PLGA with different molar feed ratio were synthesized with direct melt polycondensation. In order to increase the molecular mass of polymer, the chain extension of PLGA was carried out in melt state with 4, 4-diphenylmethane diisocyanat...
Here, the unprecedented aggregation behavior of high molar mass block copolymer poly(N,N-diethylacrylamide)-b-poly(4-acryloylmorpholine) (PDEA-b-PAM) (Mn>400kg mol-1) in organic solvent tetrahydrofuran (THF) is investigated. To elucidate the aggregation, dynamic light scattering, cryo-transmission...
CO emitted to the atmosphere shall be treated as the molar equivalent amount of CO2. Oxid uhelnatý (CO) emitovaný do ovzduší je považován za molární ekvivalent množství CO2. Eurlex2019 CO emitted to the atmosphere shall be calculated in the mass balance as emission ...
For the analysis of the phenolic compounds in the hydrotreated sugar solutions, 5 mL liquor samples were extracted three times with 5 mL of diethyl ether, after addition of salicylic acid as the internal standard. The ether phases were combined, evaporated to dryness, and analysed by GC/MS (...
Abstract: Method for producing polyacrylate adhesive compounds with a narrow molar mass distribution by radical polymerization and subsequent decolorization of colored reaction products resulting therefrom. Inventors: Prenzel, Alexander (Hamburg, DE)
The overall yield of the final NHS esters was about 75% based on mass weight of mPEG5k used. (2) mPEG5k (5.0 g), succinic anhydride (0.12 g) and p-toluenesulfonic acid (50 mg) were melted at 70°C with oil bath for 4-h reaction. The resulting intermediate was dissolved in 10 mL...
The invention relates to dental materials containing at least one polyacid or at least one polyacid and at least one salt of at least one polyacid with a molar mass distribution Mw/
