N,N-dimethyldodecylamine-N-oxid
Product name: N, N-dimethyl dodecylamine-N-oxide
CAS: 1643-20-5
Molecular formula: C14H31NO
Molecular Weight: 228.3946
Product Description: Colorless or yellow transparent at normal temperature, is a special type of surfactant, a colorless transparent liquid or yellow at room temperature it is a cationic surfactant in acid, while in a neutral or alkali to the non-ionic. In addition to the general performance of the surfactant, but also excellent solubility, thickening, emulsifying, foaming, foam, gentle, moisturizing, electrically conductive, it has good compatibility with human skin toxicity organic is small, easy biodegradation. And there was a performance and mouldproof bactericidal effect.
Trichloroisocyanuric acid
We studied the efficacy of silver oxide coating to an indwelling catheter and a urethral catheter adapter and the instillation of trichloroisocyanuric in the urine bag in the prevention of catheter bacteriuria associated with a test prospective randomized and 74 patients. Bacteriuria has been documented (39 percent) in 29 of 74 patients. There was a significant difference between incidence rates in 11 of 41 patients (27 percent) in the test group and 18 of 33 (55 percent) in the control group bacteriuria (p equal to 0.02) after a median of bacteriuria with 36 and 8 days (p = 0.01). colonization of the urethral meatus was involved as a source of bacteriuria bladder in 12 of 18 patients (67 percent) in the control group and 5 of 11 (45 percent) in the test group. Trichloroisocyanuric Drainage considerably contamination of the bag, but the contamination of the bag with the same micro-organism responsible for the infection progressing bacteriuria in only 2 of 29 patients (7 percent), 1 reduced in each group. Patients receiving systemic antimicrobials bacteriuria purchased less frequently than those who do not. The apparent protective effect of systemic antimicrobial agents was highest during the first 4 days of catheterization. Data show that the bacteriuria episodes are formed from the passage of the urethra, are common in patients catheterized and the antimicrobial catheter is effective in reducing the incidence of bacteriuria associated catheter.

Product Description: crystal fluffy bright white. Point 154-155 ℃, the relative density of 1.32, insoluble in tetrahydrofuran, cyclohexanone, acetone, alcohol, ether, slightly soluble in polyvinyl chloride (PVC) with all kinds of plasticizers insoluble in water and the fusion carbon disulfide. Flammable, bitter taste when friction.This product vulcanization accelerator is faster, especially for natural rubber latex and synthetic latex products can also be used in the manufacture of tires, pneumatic tires vulcanization capsule, the water, the son and cables, industrial products, rubber shoes, etc. This product can be used as thermal polymerization PVC emulsion stabilizer, particularly suitable for soft products, the general dosage is 0.2 to 0.5%, which makes the plastic dyes can not be used, but the product light discoloration can not prevent, with lead, cadmium stabilizers, otherwise it will result in the products change color. Diphenyl is also medicine, dye intermediates in the production of indigo, sulfide, methyl dyes of indigo and flotation agents, the protective agent acid is used, etc. This product is the determination of osmium, ruthenium chemical reagent.
What is Diphenylcarbazide
This document shows the results of the investigation into the abduction of Cr (VI) and Cr (VI) complex from aqueous solutions -diphenylcarbazide an electrochemical reactor using iron electrodes. A maximum value of 99% Cr (VI), removal of aqueous solutions, both for Cr (VI) and Cr (VI) to -diphenylcarbazide initial concentrations of 150 to 800 mg L (-1) have observed. cyclic water voltammetry experiments show the presence of the electroactive species in the oxidation zone and reduction before treatment and how presence will reduce the electrochemical treatment of the waste water is applied. UV-Vis analysis confirms treated to improve the quality of the aqueous solutions. Finally, electron microscopy show scanning and energy dispersive spectra of Cr and Fe are present as constituents of the sludge formed during the electrochemical treatment. It has been shown that the use of electrochemical methods for the treatment of Cr (VI) and Cr (VI) aqueous solutions -diphenylcarbazide is an efficient and economical process.
