neutralization reaction
1.Abstract: The equilibrium constant of carbonization reaction of lime white was calculated using three thermodynamics methods.The results indicate that the carbonization reaction of lim white was the neutralization reaction between acid and alkali first,and it was the transform reaction of precipitation second .The essential cognition of the carbonization reaction of lime white was deepend.It was of guiding significance for industrial production of light(precipitation)calcium carbonate.
2.Nineteen cultures of phage attacking S. spiramyceticus were isolated from the abnormal fermentation liquid and soil samples. Phages were purified and classified into four serotype according to the serological neutralization reaction. The phage plaque of 1010 and 4031 were large and translucent, and Pll and 1012 were small and transparent.
3.When the treating technology of DSD acid production wastewater was transformed into "Electrolysis-Neutralization sedimentation-Anaerobic baffled reaction-Contact oxidation-Sedimentation-Chemical oxidation",COD and colors of the outflow were below 500 mg/L and 400 times lower,respectively. The treatment cost was 4.94 Yuan/m~3 water and 0.66 Yuan/kg COD,so it is economical.
4.That the 3G_1 clone showed considerably high neutralization and HI activites as well as cross reaction with A_(35) (anti-NP) in RPHI. Tish indicates that 3G_1 might be a special MeAb which can recognize both envelope and nucleocapsid proteins.
5.By the methods of enzyme immuno-assay ( EIA ) and neutralization test ( NT ) , MD orbivirus showed no cross-reaction with BANNA orbivirus isolated from patients with FUO, and two other orbivirus isolates, YN187 and Ml49 isolated from mosquitoes.
6.The optimum reaction conditions are(0.95)×10~(-5) molar ratio of crosslinking agent to acrylic acid,(4.8)×10~(-3) molar ratio of initiator to acrylic acid,71% neutralization degree of acrylic acid,polymerization at 45 ℃ and 2 h.
7.Methods Applying reverse transcriptase polymerase chain reaction (RT PCR) to semiquantitatively analyse the enterovirus RNA and using neutralization test to detect the neutralizing antibody in peripheral blood from 16 PM/DM patients and 10 normal individuals.
8.Chemical reaction of plagioclase +biotite +quartz mineral mixture with 1.0 mol/L NaCl or 0.5 mol/L NaCl +0.5 mol/L NaHCO3 solution at 450～250 ℃and 50 MPa for 7 d shows that after reaction NaCl solution becomes more acidic, while NaCl +NaHCO3 solution tends to be more neutralization, and that the concentration of K, Ca, Mg, Fe and Au in the solution changes.
9.The result shows the High Performance Concrete (HPC) with low W/B normally has denser surface, consuming the Ca(OH)2 by pozzolanic reaction and low permeability, which are allowed to restrain effectively the neutralization to decrease the cracking for better durability on concrete.
