Application

1-Bromohexadecane has been used:
  • in the preparation of soluble carbon nano-onions by covalent functionalization with hexadecyl chains[1]
  • as extraction solvent in determination of endocrine-disrupting phenols (EDPs) in water samples by ultrasound-assisted emulsification microextraction (MS-USAEME) method[2]
  • in the preparation of [2-(methacryloyloxy)ethyl]dimethylhexadecylammonium bromide monomer, required for the synthesis of novel methacrylate based adsorbents[2]
  • in the synthesis of surfactant, N-hexadecyl ethylenediamine triacetic acid (HED3A)[3]

Manual shaking-enhanced, ultrasound-assisted emulsification microextraction (MS-USAEME) combined with ultraperformance liquid chromatography (UPLC) with UV detection has been developed for the determination of five endocrine-disrupting phenols (EDPs) in seawater samples and detergent samples: 4-tert-butylphenol (4-t-BP), 4-cumylphenol (4-CP), 4-tert-octylphenol (4-t-OP), 2,4-di-tert-butylphenol (2,4-di-t-BP)

Herein we report the preparation of truly soluble CNOs by covalent functionalization with hexadecyl chains. These compounds are prepared in two steps: first, reduction of CNOs with a Na-K alloy in 1,2-DME under vacuum, followed by nucleophilic substitution employing 1-bromohexadecane.

A new kind of surfactant named N-hexadecyl ethylenediamine triacetic acid (HED3A) was synthesized from anhydrous ethylenediamine, 1-bromohexadecane, and chloroacetic acid. Testing showed stability of HED3A in hard water, wetting power, dispersing power, and surface tension increased along with pH value.

The Oil Transfer Technique (OTT) was developed by Taisne et al. [1] to measure coalescence during emulsification and has been applied since in several studies. One of the main drawbacks of this technique is that it only gives a qualitative

Biofilms at the tooth-restoration bonded interface can produce acids and cause recurrent caries. Recurrent caries is a primary reason for restoration failures. The objectives of this study were to synthesize a novel bioactive dental bonding agent containing dimethylaminohexadecyl methacrylate (DMAHDM)
