Product Description

Tris(hydroxymethyl)aminomethane, Tris or THAM for short, is usually used in biological buffers, such as Tris base, Tris hydrochloride, Tris acetate, etc. In fact, it is also used in many new materials. This article introduces Tris in Application in the research of new functional crystals.
 
Tris and arsenic acid generate large organic single crystals
Tris and various acids can form different salts, such as hydrochloric acid, carbonic acid, acetic acid, boric acid, glycine, etc., which are mainly used as buffers. Tris reacts with acid, and some can form new compound crystals. For example, it can form tris(hydroxymethylaminomethane) arsenate THAMAS with arsenic acid. This is a new organic crystal that can grow optical quality from aqueous solution by cooling down. Large single crystals (small crystals arranged in disorder are polycrystals).
 
New optical organic crystal Tris arsenate
The research of new functional crystalline materials has always been a very popular field in materials science. Organic compounds containing amino groups such as Tris can form new organic crystals with acids. TGS (Triglycine Sulfate) crystals have been extensively studied and applied, and Glycine (glycine) and oxalic acid produce two kinds of organic crystals, GO and DGO. The growth, structure, optical properties, research and application of single crystals of new organic crystals such as Tris arsenate formed by Tris and acid are still being developed.
 
Growth of Tris Arsenate Single Crystal
Using biochemical grade Tris and analytical pure arsenic acid H2As2O4 as raw materials, using distilled water as a solvent, the solution is prepared in an equal molar ratio, and a transparent single crystal with a complete shape is obtained through spontaneous nucleation by cooling or evaporation. After thermogravimetric analysis, it is shown that the Tris arsenate crystals do not contain crystal water. Using small crystals obtained by spontaneous nucleation as seed crystals (seed crystals), large single crystals with optical quality can be obtained by the cooling method, and the growth rate can be **3mm/d along the crystallographic b-axis direction (**0).
 
Tris arsenate crystal structure and optical properties
The X-ray diffraction data of Tris arsenate single crystal was collected with a diffractometer. It appears that it is a monoclinic crystal system at room temperature, and the space group is P**1. Measure the light transmission curve of the crystal with a spectrometer. The surface is a two-axis negative optical crystal on the surface. For the NaD line, the optical axis angle is 2V=*9.2 degrees.
 
In addition to being used for optical crystal materials, Tris can also be used for fireproof materials, new water-based coatings and so on. Desheng is a manufacturer of Tris, which can provide large quantities of reagent grade and industrial grade Tris raw materials.
