摘要:洛普唑仑 (1) 在酸性缓冲液 (Ph 2.8) 中的汞滴电极处分三个阶段 (Dct) 还原.第一阶段 (A) 对应于其 No2 基团还原为羟氨基阶段 (4 θ),第二阶段 (B) 对应于oc N 双键 (5,6) (2 θ) 的还原,最负电位 (C) 的阶段被指定为丁氮二烯基团 (4.) 的还原.只有在强酸性缓冲液 (Ph <2.8) 中,质子化的羟氨基也被还原为 R-Nh2,因此在这种情况下,所有阶段的总消耗量为 12 θ.

摘要:A composition having a mixture of the below compounds having a mole ratio of at least 1:20. Ar 1 and Ar 2 are independently selected aromatic groups. A composition comprising phthalonitrile compounds that comprise at least 5 mol % of the first compound below. n nA method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; a dihydroxyaromatic compound or anion thereof; an organic transition metal complex or a transition metal salt; an alkaline hydroxide base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form a dimetallic salt of an aromatic ether oligomer. The molar ratio of the dihydroxyaromatic compound to the dichloroaromatic compound is greater than 2:1. Water formed during the heating is concurrently distilled from the solution.

摘要:A method of: providing a solution of a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; an excess of a dihydroxyaromatic compound; an organic transition metal complex or a transition metal salt; a base; and a solvent; and heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form an aromatic ether oligomer that is a dihydroxy-terminated compound or a dimetallic salt thereof. Water formed during the heating is concurrently distilled from the solution. A method of curing a phthalonitrile monomer in the presence of an acid and a curing agent to form a phthalonitrile thermoset.
