Cetyl Trimethyl Ammonium Bromide

Details:

Products：Cetyl Trimethyl Ammonium Bromide

CAS NO.:  57-09-0          Moecular Wleight：364.446

Molecular Formula：C₁₆H₃₃(CH₃)₃ NBr      Pack:10KG/B

Physicochemical property:

 Product is white or light yellow crystalline powder, soluble in methanol, ethanol and isopropanol (> 200 g/L, 20 ° C), soluble in water (13 g/L, 20 ° C), produced in lots of bubble oscillation, slightly soluble in acetone, hardly soluble in ether, chloroform and benzene.The cation active group is dissociated in water and has good emulsifying effect.In water, it has good emulsification of mineral oil, animal and plant oil, synthetic oil, etc., and is not affected by PH value.It has good compatibility with cationic, non-ionic and amphoteric surfactants, good permeability, flexibility, emulsification, antistatic, biodegradability and sterilization.Good chemical stability, heat resistance, pressure resistance and strong acid and alkali resistance, moisture absorption.

Useage:

1, preparation of purified DNA，It can be used to prepare purified DNA from a large number of mucopolysaccharide producing organisms such as plants and certain gram-negative bacteria (including some strains of e.coli).

2，Extract whey protein

    The foam produced by CTAB beating can separate whey proteins, and more than 80% of the individual proteins can be obtained.The polar non-region of CTAB contains positive charge, and the isoelectric point of most whey proteins in whey is below PH5.5, while the surface of protein in normal whey fluid (PH6.5) is negatively charged, and the binding of protein particles and CTAB leads to electrostatic binding, forming whey protein-ctab complex.

3，Synthetic coumarin

Coumarin was synthesized by perkin reaction using CTAB as activator, anhydrous potassium carbonate as catalyst, salicylaldehyde and acetic anhydride as raw materials.CTAB can effectively activate the catalyst anhydrous potassium carbonate, increase its alkalinity, and increase the yield of coumarin to 85.3%.

Notes:   Store in dry and cool place.
