摘要： A new mono-silylating agent of general formula (I)
(R₁,R₂,R₃)Si-NH-CO-O-Si(R₁,R₂,R₃) (I)
is described as well as its use in the preparation of chromatographic supports based on silica with functional groups covalently bonded thereto, the so-called "bonded stationary phases".
The new compounds are easy and safe to prepare from the corresponding mono-halosilanes with ammonium carbamate, and their use as silylating agents leads to stationary phases with a higher degree of surface coating than that attainable with the corresponding chlorosilanes.摘要翻译： 描述了通式（I）（R1，R2，R3）Si-NH-CO-O-Si（R1，R2，R3）（Ⅰ）的新单甲硅烷基化剂及其在色谱法制备中的应用 基于与其共价键合的官能团的二氧化硅的载体，即所谓的“键合固定相”。 新化合物由相应的单卤硅烷与氨基甲酸铵制备容易和安全，并且它们作为甲硅烷基化剂的用途导致具有比相应的氯硅烷可获得的更高程度的表面涂层的固定相。

摘要： This invention firstly provides a method for purifying particular compounds of peptide or pseudo-peptide structure in which the number of protonable basic functions is greater than the number of acid functions and which have a molecular weight of less than 1000 daltons, by ion exchange displacement chromatography. In the method of the present invention the stationary phase used is a cationic exchange resin or a cross-linked polymer matrix activated with acid groups; the transporter solvent used is water if the compound to be purified already possesses at least one net positive charge, or aqueous dilute solutions of inorganic or strong organic acids which protonate the basic groups of the peptide or pseudo-peptide to be separated without modifying the structure of the peptide compound, such as acetic acid, trifluoroacetic acid, formic acid, hydrochloric acid or sulphuric acid; the displacer compound used is a triethylenetetraammonium salt.
