テトラキス(ヒドロキシメチル)ホスホニウム クロリド (約80% 水溶液) 化学特性,用途語,生産方法
化学的特性
Clear light pink or yellow-green solution
使用
Tetrakis(hydroxymethyl)phosphonium chloride solution (80% in H
2O) has been used as a reducing agent and stabilizing ligand for the synthesis of gold nanoparticles (AuNPs) from gold(III) chloride trihydrate (HAuCl
4.3H
2O). It is a tetra-functional, amine-reactive, aqueous crosslinker that can be used for tuning the properties of protein-based hydrogels for 3D cell encapsulation applications.
定義
A crystalline compound made by the reaction of
phosphine, formaldehyde, and hydrochloric acid.
一般的な説明
Clear slightly viscous,colorless to yellow liquid (20% H2O solution).
空気と水の反応
Hygroscopic. Water soluble.
反応プロフィール
Tetrakis(hydroxymethyl)phosphonium chloride reacts vigorously with oxidizers and alkalis. Reacts with cellulose.
健康ハザード
ACUTE/CHRONIC HAZARDS: Tetrakis(hydroxymethyl)phosphonium chloride may be corrosive. When heated to decomposition, it may emit very toxic fumes of POx, hydrogen chloride and bis(chloromethyl)ether. Decomposition of Tetrakis(hydroxymethyl)phosphonium chloride in an aqueous environment may produce phosphine, formaldehyde and hydrogen chloride.
火災危険
Tetrakis(hydroxymethyl)phosphonium chloride is probably combustible.
純化方法
Crystallise it from AcOH and dry it at 100o in a vacuum. An 80% w/v aqueous solution has d4 1.33 [Reeves J Am Chem Soc 77 3923 1955]. [Beilstein 1 IV 3062.]
