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.
Tris(2-aminoethyl)amine synthesis process
-
Paragraph 0020; 0024-0032, (2019/03/31)
The invention discloses a tris(2-aminoethyl)amine synthesis process, and belongs to the technical field of compound preparation. The tris(2-aminoethyl)amine synthesis process includes the steps of taking triethanolamine as a starting material, putting the triethanolamine, thionyl chloride and a catalyst DMF in a reactor, heating the three to generate tris(2-chloroethyl)amine hydrochloride, dissolving separated tris(2-chloroethyl)amine hydrochloride concentrate and ammonia water in an organic solvent in a reactor, putting the solution in the reactor, carrying out a reaction while heating to obtain tris(2-aminoethyl)amine hydrochloride, and reacting the tris(2-aminoethyl)amine hydrochloride with sodium hydroxide to obtain the tris(2-aminoethyl)amine. The tris(2-aminoethyl)amine synthesis process has the advantages of short reaction route and high controllability.
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.
