While trying on the one-step process for polyacrylonitrile manufacture by usingmethlallylsulfonate as the third monomer and sodium thiocyanate as the solvent,theauthors found that the viscosities of the polyacrylonitrile copolymers were quite differentfor various consignments of sodium thiocyanate used.A thorough investigation by meansof infrared spectrophotometric and other chemical methods revealed that sodium formatewas the principal impurity in the sodium thiocyanate.Experiments have shown that thepresence of sodium formate has a serious influence on the acrylonitrile-methacrylate-methylallylsulfonate copolymerization in a concentrated aqueous solution of sodium thiocyanate.It is therefore suggested that,in the production of polyacrylonitrile,thesodium formate content be taken as an important criterion for determining the quality ofthe sodium thiocyanate.Meanwhile,a method to determine the sodium formate content insodium thiocyanate is suggested.The authors adopted the silve nitrate precipitationmethod in an alkaline medium in order to eliminate the interference of CNS ions;thenthey titrated the sodium formate in the filtrate by the common permanganate iodimetricmethod.The method is simple,concise and reproducibe.The relative error is below 1%when the content of sodium formate exceeds 0.5%.It provides a method for industrialanalysis.

在以甲基烯丙基磺酸钠为第三单体,硫氰酸钠为溶剂的腈纶一步法工艺试验中,发现用不同批号的硫氰酸钠所得聚丙烯腈共聚物的粘度相差很大,经用红外光谱法、化学分析法等方法鉴定出硫氰酸钠中的主要杂质为甲酸钠。经过试验证明甲酸钠对硫氰酸钠浓水溶液中丙烯腈—丙烯酸甲酯—甲基烯丙基磺酸钠的共聚有严重的影响。因此建议硫氰酸钠中甲酸钠的含量可以作为腈纶生产中考核硫氰酸钠质量的一个重要指标,同时提出了硫氰酸钠中甲酸钠含量的测定方法。此法采用碱性介质中硝酸银沉淀法,除去 CNS-的干扰,然后用高锰酸钾—一碘量法测定滤液中的甲酸钠。操作较简便,数据重现性好,甲酸钠含量在0.5%以上,相对误差在1%以内。可供工业分析之用.

As compared with the quantitative chemical procedure, this method is simple, rapid, likely to get more determinable calcium bilirubinate, and other organic elements present in the stone can also be detected simultaneously.Either for qualitative or quantitative analysis, this method has its superiority.

An infrared spectrophotometric method was used to determine the calcium bilirubinate and cholesterol contents in human gallstone. As compared with the quantitative chemical procedure, this method is simple, rapid, likely to get more determinable calcium bilirubinate, and other organic elements present in the stone can also be detected simultaneously.Either for qualitative or quantitative analysis, this method has its superiority. Altogether, 340 consecutive specimens were studied, based on the data obtained from the quantitative analysis. In recent years, there has been a tendency that the incidence of cholecterol stones (CS) of the gallbladder is increasing while that of pigment stones (PS) of the bile duct is decr-easing. For instance,in 1973-1977, the ratio of CS to PS was 1:1.63, and that of the gallbladder calculi to bile duct once was 1:1.36; while in 1978-1982 the ratios of 1:0.89 and 1:0.88 were observed respectively.

红外光谱澳化钾压片法,测定胆石中的胆红素钙和胆固醇含量,方法较化学定量法简便,快速。胆红素钙测定量提高,同时还可测得结石中的其他有机成分。无论用作胆石定性或定量均有优越性。用红外光谱定量分析研究解放军总医院340例连续留取的胆石标本,前5年与后4年比较,胆囊与胆管结石之比从1:1.36降至1:0.88;胆固醇结石与胆红素钙结石之比从1:1.70降至1:0.89。由于我院收治对象未变,历年来均以北京地区病人为主,故也在一定程度上反映了北京地区胆结石部位及成分变动的趋势。

The kinetics of oxidation and isomerization of rare-earth polyacetylene (Ln-PA) and its elastomer composite films (PA/SBR,PA/EPDM) exposed to ambient air at~20℃ have been established by infrared spectrophotometric analyses.The IR spectrum of the sample stored for some time shows several new absorption bands:1675 cm-1,1730cm-1,and 3480cm-1,corresponding to a,p-unsaturated ketone,a-diketone,and hydroxyl or perhydroxyl groups formed,respectively.Oxidation of rare-earth PA and its elastomer composite films...

The kinetics of oxidation and isomerization of rare-earth polyacetylene (Ln-PA) and its elastomer composite films (PA/SBR,PA/EPDM) exposed to ambient air at~20℃ have been established by infrared spectrophotometric analyses.The IR spectrum of the sample stored for some time shows several new absorption bands:1675 cm-1,1730cm-1,and 3480cm-1,corresponding to a,p-unsaturated ketone,a-diketone,and hydroxyl or perhydroxyl groups formed,respectively.Oxidation of rare-earth PA and its elastomer composite films is a first-order process comprised of one or two distinct regions,which is similar to those of Ti-PA.However,they have longer induction periods of oxidation and lower rate of oxidation as compared with Ti-PA.Cis-trans isomerzation of the samples also shows two first-order domains,and the rate of isomerization is smaller than that of Ti-PA.The antioxidation and anti-isomerization ability of various PA films decreases in the following order:PA/EPDM>PA/SBR>Ln-PA>Ti-PA,

用红外分析初步研究了稀土聚乙炔(Ln-PA)及其弹性体复合膜(PA/SBR,PA/EPDM)在室温(~20℃)空气中的氧化及异构化动力学行为。氧化聚乙炔在1675cm~(-1),1730cm~(-1)和3480cm~(-1)出现相应为及的特征吸收。氧化过程是由一个或两个单独区域组成的一级动力学过程,与Ti-PA相似,但较Ti-PA有更长的氧化诱导期和低的氧化速率。异构化过程也分成两个一级动力学区域。各种膜的耐氧化及抗异构化能力的次序相同:PA/EPDM>PA/SBR>Ln-PA>Ti-PA。在聚乙炔中加入弹性体可提高膜的耐氧化性和延缓顺/反异构化的过程。
