  日期：——

  homogeneous sulfonations of 1,3-dihydroxybenzene (1), its monomethyl (2) and dimethyl ether (3) in concentrated aqueous sulfuric acid at 25°C have been studied and isomer distributions and rate coefficients for the sulfonation of 1–3 and their monosulfonic acids are reported. The initial process, upon dissolution of the reactants, is protonation at C(4) and C(6). The subsequent sulfonation of the symmetrical

  研究了1,3-二羟基苯（1），其单甲基（2）和二甲醚（3）在25°C浓硫酸中的均相磺化反应，以及异构体分布和磺化1〜3和2的速率系数。报道了它们的单磺酸。反应物溶解后的初始过程是在C（4）和C（6）质子化。随后对称反应物1和3的磺化反应生成4-磺酸，而2和2的4-和6磺酸在73.5％H 2 SO 4下的比率为0.8 + 0.1 。1的4-磺酸的磺化（1 -4-S）产生2,4-和4,6-二磺酸的混合物，2 -4-S和3 -4-S产生4,6-S 2和2-6 -S给出2,6-和4,6-S 2的混合物。二磺酸1 -2,4-S 2和2 -2,6-S 2均缓慢异构化，得到4,6-二磺酸异构体。在酸浓度≥82.8％H 2 SO 4时，1的二磺酸缓慢生成1 -2,4,6-S 3，而2和3的二磺酸则缓慢生成1 -2,4,6-S 3。不进一步磺化。不存在的2 -2,4-S 2从2 -4-S和2 -2,4,6--S

  Permeable, porous polymeric membrane with hydro­philic character of the membrane, said character being obtained by treatment with a solution com­prising one or more hydrophilic, mono-or polymeric compounds selected among soluble, OH-containing cellulose derivatives, polyvinylalcohols and low molecular weight, polyfunctional, NH-and/or OH-­containing compounds, optionally in the presence of a cross-linking agent, a surfactant and a initia­tor followed by rendering the layer deposited during the treatment insoluble on the membrane surface by means of a catalyst reaction at elevated tempera­tures in order to fixate the hydrophilic material to the membrane. Furthermore a process for the preparation of these membranes by means of treating a permeable, porous, polymeric membrane of hydro­phobic character with the above solution in the presence of a catalyst and optionally in the pre­sence of a cross-linking agent, a surfactant and an initiator, and curing of the coated membrane by means of heating to form an insoluble, hydrophilic surface layer. The membranes are suitable for use in ultra- and microfiltration.
