CAS :1,1,3,3-Tetramethyldisiloxane is a chemical compound that belongs to the group of functional groups. It can be isolated from hydrolysis of methyltrichlorosilane with sodium hydroxide and cellulose acetate. 1,1,3,3-Tetramethyldisiloxane has two isomers with different properties: 3-methylsilsesquioxane and 3-ethylsilsesquioxane. The former has an ethyl group at the end of its molecule and the latter has an ethyl group in the middle. The two isomers are not interchangeable because they have different physical properties. The 3-methylsilsesquioxane isomer reacts with aluminium to form a metathesis reaction product containing silanol groups on one side of the aluminum molecule and hydroxy groups on the other side. This product can be used as a catalyst for subsequent reactions in organic synthesis reactions involving

Formule :C14H19BO4Degré de pureté :Min. 95%Masse moléculaire :262.11 g/molTriethyl borate
CAS :Triethyl borate is an inorganic acid that is used as a catalyst. It has been shown to react with hydrochloric acid and orthoboric acid to form hydrogen boron hydride (H3BO3) and water. It also reacts with hydrogen chloride, forming hydrogen boron chloride, which can be used to prepare the active form of boric acid. This reaction is reversible and the equilibrium can be shifted by adding a base such as sodium hydroxide or ammonia. Triethyl borate is reactive, so it should only be handled in well-ventilated areas. The structural analysis of this compound reveals that it contains two hydroxyl groups that are involved in intramolecular hydrogen bonding, which helps stabilize its structure. Triethyl borate has been shown to have anti-infectious properties, inhibiting the growth of infectious bacteria such as Staphylococcus aureus and Streptococcus pneumoniae.
