    With a view to getting rid of unlevel dyeing effects of conventional cationic dyes on acrylic fibers, a migrating cationic red, Migrating Cationic Red Ⅰ by name for the time being, has been prepared. The route for its synthesis has been selected from among several feasible ones through experimentation as well as through a brief review of the literature. After coupling diazotized p-chloroaniline with imidazole, the resulting monoazo dye is quaternized with dimethyl sulfate. Upon dimethylamination, the quaternary...

    With a view to getting rid of unlevel dyeing effects of conventional cationic dyes on acrylic fibers, a migrating cationic red, Migrating Cationic Red Ⅰ by name for the time being, has been prepared. The route for its synthesis has been selected from among several feasible ones through experimentation as well as through a brief review of the literature. After coupling diazotized p-chloroaniline with imidazole, the resulting monoazo dye is quaternized with dimethyl sulfate. Upon dimethylamination, the quaternary ammonium, compound thus formed yields the title dye.

    为了免除习用阳离子染料对聚丙烯腈纤维染色不匀的影响,本文制得暂行定名为迁移性阳离子红(Ⅰ)的红色染料。其合成路线经由文献简评、並由实验从若干可能路线中予以选定。对-氯苯胺重氮化后,与咪唑偶合,生成单偶氮染料,与硫酸二甲酯季铵化,所得季铵化合物再经二甲胺基化即为题示染料。

    The synthesis of a series of monoazo disperse dyes is described of which the basic formula is as the following: where x stands for a NO_2 or a CN-group, while Y for a CN-group, a bromine atom or a hydrogen atom; R will represent a CH_3O-group or a hydrogen atom; R'will represent a CH_3-, a C_2H_5-, a C_2H_4OCH_3- or a C_2H_4OC_2H_5-radical.The dyes will give the polyester fiber a bright shade, from reddish violet to greenish-blue, and shows good liglt, weather and sublimation fastness.Good correlation...

    The synthesis of a series of monoazo disperse dyes is described of which the basic formula is as the following: where x stands for a NO_2 or a CN-group, while Y for a CN-group, a bromine atom or a hydrogen atom; R will represent a CH_3O-group or a hydrogen atom; R'will represent a CH_3-, a C_2H_5-, a C_2H_4OCH_3- or a C_2H_4OC_2H_5-radical.The dyes will give the polyester fiber a bright shade, from reddish violet to greenish-blue, and shows good liglt, weather and sublimation fastness.Good correlation has been found between the absorption maxima of these dyes and their solubility parameters calculated is in good agreement to that of the fibre.The introduction of the cyano group into the diazo component renders the mon oazo disperse dyes to have a greater bathochromic effect, upon which the high absorption coefficient, smaller bundwidth the exhibition of a brighter and purer shade as well as absorption intensity and inprovement of light fastness may be apparently explained.

    以2-氰基-4-硝基苯胺、2-氰基-4-硝基-6-溴苯胺、2,4-二硝基-6-溴苯胺、2,6-氰基-4-硝基苯胺和2,4-二硝基-6-氰基苯胺为重氮组份与端氨基含醚基的偶合组份经重氮化、偶合合成了一系列红光紫——绿光蓝色单偶氮分散染料。在涤纶纤维上,其中一些染料的色泽比较鲜艳,强度较高並有较为满意的耐晒、耐气候和耐升华牢度。测定了染料在丙酮中的最大吸收波长和摩尔吸光系数,计算了它们的溶解度参数。对染料的结构和颜色之间的关系进行了讨论。对国内外学者在重氮组份氨基邻位引入氰基的原因也作了探讨,主要是由于氰基比其他吸电子基团有较大的深色效应,赋予染料以较为鲜艳和纯正的色光、较高的吸收强度和牢度性能。

    The permeability of the cell membrane of yeast is the main factor whic imits the enzymic phosphorylation synthesis of ATP when yeast used. It h is obvious that different pertreatment has diffevent effect on permeability of cell membrane for different strains of yeast. The membrane permeabilitie -s of the beer yeast soaked by cold water and the bread yeast dried by the sunlight are so slightly increased that the enzymatic phosphorylation synthe -sis of ATP can carry out within the cells. Therefore this will provide a good condition for the cell to be immobilized for produsing ATP in industr -y. The membrane permeability of the stoved bread yeast and the frozen white wine yeast are too greatly increased to keep the enzymatic phosphorylation to take place neither in nor out of the cells. The expeiment alro proves that glucose can faci-litate the release of hexokinase from the white wine yeast cell. Thus we can extract enzyme liguid with glucose, or make further immobilized enzyme system for broducing ATP industrially.

    酵母用于酶促磷酸化合成ATP主要受酵母细胞膜渗透性限制。显然,不同的预处理对不同菌株酵母细胞膜的渗透性有不同的影响。冷水浸洗的啤酒酵母和日晒干燥的面包酵母,其细胞膜的渗透性稍有提高,酶促磷酸化反应可在细胞内进行。因而可提供固定化细胞的条件,用于工业生产ATP。烘干的面包酵母和冰冻的白酒酵母,其细胞膜的渗透性大幅度增加,致使酶促磷酸化反应既不能在细胞内,也不能在细胞外进行,实验还证明,葡萄糖对白酒酵母细胞中的已糖激酶释放有促进作用,因而可用以提取酶液,或进一步制成固定化酶,工业生产ATP。
