(3-меркаптопропил)триметоксисилан

Химические свойства

Water white to light straw liquid clear liquid with an unpleasant odour of sulphide.

Использование

(3-Mercaptopropyl)trimethoxysilane is used as a capping molecule for cadmium sulphide nanocrystals. It is used in the preparation of multi-walled carbon nanotubes and bilayer modified gold electrode. It acts as a linker molecule used in the preparation of gold multilayers and as a molecular adhesive in the fabrication of vapor-deposited gold electrodes on glass substrates. It is also used as a precursor for silica.

прикладной

MPTMS can be coated with TiO₂, CeO₂ and La₂O₃ for protection against corrosion on quaternary bronze in urban atmosphere. It can also be used as a silica nanofluid (NF) to modify the surface of berea sandstone to improve the enhanced oil recovery (EOR) area in the petroleum industry. MPTMS forms composites with kaolin, that can be used as an absorbent for the removal of heavy metals from wastewater. MPTMS can form a bilayer with multiwalled carbon nanotubes (MWNTs) on gold electrodes which can be used to study the electrochemical properties of fluphenazine.

Подготовка

(3-Mercaptopropyl)trimethoxysilane was prepared by using thiourea and 3-chloropropyltrimethoxysilane as raw materials, petroleum ether as solvent, KI as catalyst, and ethylenediamine as neutraliser.

Общее описание

(3-mercaptopropyl)trimethoxysilane (MPTMS) is an organosilane with a thiol group, which can be used as a self-assembled monolayer (SAM). It can be used as a conjunction reagent to immobilize a variety of nanoparticles.
