Usage

General Description

Trimethyltetradecylammonium hydroxide, also known as TTDAH, is a quaternary ammonium compound used as a surfactant and emulsifier in various industrial and consumer products. It is a member of the ammonium quaternary compounds, which are known for their antimicrobial and detergent properties. TTDAH is commonly used in fabric softeners, hair conditioners, and industrial cleaning products due to its ability to reduce surface tension and improve wetting and dispersing properties. It is also used in the synthesis of organic chemicals and pharmaceutical products. However, it is important to handle TTDAH with caution as it can cause skin and eye irritation and is considered toxic if ingested or inhaled.

Phase behaviors and self-assembly properties of two catanionic surfactant systems: C8F17COOH/TTAOH/H2O and C 8H17COOH/TTAOH/H2O

Two fatty acids, perfluorononanoic acid (C8F17COOH) and nonanoic acid (C8H17COOH), were mixed with a cationic hydrocarbon surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), in aqueous solutions for comparative investigation. Phase behaviors of the two systems are quite different because of the special properties of the fluorocarbon chains. For the C8H17COOH/TTAOH/H 2O system, a single Lα phase region with phase transition from planar lamellar phase (Lαl phase) to vesicle phase (Lαv phase) was observed. For the C8F 17COOH/TTAOH/H2O system, two single phases consisting of vesicles were obtained at room temperature. One is a high viscoelastic gel phase consisting of vesicles with crystalline state bialyers at the C 8F17COOH-rich side, which was confirmed by freeze-fracture transmission electron microscope (FF-TEM) and differential scanning calorimetry (DSC) measurements. With the increase of TTAOH proportion, another vesicle phase consisting of liquid state bilayers was observed after the two-phase region. The fluorosurfactant systems prefer to form vesicle bilayers than the corresponding hydrocarbon ones because of the rigid structure, the stronger hydrophobicity, and the larger volume of fluorocarbon chains.

Niobium peroxide-catalyzed selective epoxidation of allylic alcohols

Modified niobium peroxides were prepared and used for catalyzing the epoxidation of allylic alcohols with hydrogen peroxide in the absence of any other solvent under ice bath conditions. Niobium peroxides modified with ionic liquid-type 1-dodecyl- 3-methylimidazolium hydroxide or conventional tetradecyl trimethyl ammonium hydroxide surfactants demonstrated excellent yields (80-99%) for the epoxidation of allylic alcohols to their epoxides even if the reaction was performed without any other solvent at 0°C for 0.5 h. The catalyst characterization demonstrated that the surfactant molecules were anchored on the surface of the niobium catalyst by weak noncovalent interactions. Compared with niobium peroxides, the modified amphiphilic catalysts allowed easier accessibility to hydrophobic substrates and thus demonstrated high reaction rate and excellent recyclability for the epoxidation under mild conditions.
