N - alkylated three amidogen star-shaped ultra-low molecular inhibitors of preparation method
-
Paragraph 0037-0043, (2019/07/04)
The invention discloses a N - alkylated three amidogen star-shaped ultra-low molecular inhibitors of the preparation method, the method using triethanolamine as raw materials, in solution to the triethanolamine sequentially carry out the oxidation reaction, amination reaction, so as to obtain the final product The process of the invention is simple, low cost, mild condition, the safety is good, high yield, is suitable for industrial production. The invention prepared three amidogen N - alkylation of star-shaped ultra-low molecular inhibitor molecule with the size of the structure can be accurately controlled, the terminal group to a primary amine group and group large characteristic of the density, the bentonite and be better hydration of the stolen are there is a strong function of inhibiting, at a relatively low quantity that can effectively inhibit hydration under expansion, has strong of temperature performance, which is capable of reach 220 °C.

Paragraph 0025; 0027; 0028; 0030; 0031; 0033, (2019/04/13)
The invention discloses a preparation method of tris(2-aminoethyl)amine, and belongs to the technical field of compound preparation. According to the method, trolamine is used as starting materials; firstly, the trolamine, thionyl chloride and catalysts DMF are put into a reactor; under the heating conditions, tris(2-chloroethyl)amine hydrochloride is generated; then, the purified tris(2-chloroethyl)amine hydrochloride and ammonium hydroxide are dissolved into an organic solvent and put into the reactor; reaction is performed under the heating condition to obtain the tris(2-aminoethyl)amine hydrochloride; finally, the tris(2-aminoethyl)amine hydrochloride reacts with sodium hydroxide to obtain tris(2-aminoethyl)amine. The reaction route is short; the controllability is high.
Synthesis and interconversions of azagermatranes
Wan, Yanjian,Verkade, John G.
, p. 79 - 81 (2008/10/08)
The syntheses of the first examples of the title compounds, namely, ZGe(NRCH2CH2)3N (4, R = H, Z = Me; 5, R = Me, Z = Me; 6, R = H, Z = t-Bu; 7, R = Me, Z = t-Bu; 8, R = Me, Z = NMe2) are reported. Syntheses of the new compounds MeGe(NMe2)3 and t-BuGe(NMe2)3 and an improved synthesis of Ge(NMe2)4 are also recorded. The azagermatranes 5 and 7 are transformed to 4 and 6, respectively, in the presence of (H2NCH2CH2)3N. This reaction was not found to be reversible, however. Azagermatranes 4 or 5 and 6 or 7 in the presence of (HOCH2CH2)3N easily react to give MeGe(OCH2CH2)3N and t-BuGe(OCH2CH2)3N, respectively. Because of steric factors, one or more of compounds 6-8 may display weakened transannular Ge←N bonding or even an absence of this bonding.
