Scientists do not know exactly what causes acrylamide to form but they believe it occurs as a result of a chemical process during baking, frying, grilling or toasting.
以丙烯酸、丙烯酰胺、-丙烯酰胺 - -甲基丙磺酸为原料 ,过硫酸钾为引发剂 ,N ,N -亚甲基双丙烯酰胺为交联剂 ,环己烷为连续相 ,水为分散相 ,以Span - 0为悬浮分散剂 ,用反相悬浮聚合法合成了一系列高吸水性树脂 ,考察了合成条件对树脂吸水率的影响。
A series of high water absorbency resins was synthesized means of inverse suspension polymerization with acrylic acid (Ac) and acrylamide (Am) and 2-acrylamino-2-methylpropane sulfonic acid (Amps) as raw materials, potassium persulfate as initiator, N,N-methylenebisacylamied (Bis) as crosslinker,cyclohenxane as continuous phase, water as dispersed phase and Span-6as disperser. The effects of synthesis conditions on high water absorbency resins were studied.
中原油田将新研制的耐温 (90℃ )、耐矿化度 (1.6× 5mg/L)的丙烯酰胺三元共聚物中试胶状体产品用于小规模矿场驱油试验 ,发现现场配制的溶液粘度较中试初期产品溶液粘度室内测定值下降 9%。
A newly developed heat resistant (90℃) and salts tolerant (TDC≤1.6×mg/L) terpolymer of acrylamide is put into enlarged experiments of synthesis in small batches as solid gel and used in a pilot polymer flooding trial at Zhongyuan. It is observed in the flooding trial that the viscosity of solution prepared at the site is lower 69% than that determined in laboratory (η 0) for first experimental tercopolymer samples.
A Concentrated W/O Emulsion and the Graft Polymerization Within "Polyhedral Cells" of Acrylamide with Starch
In order to ascenian the genetic divergence level of populations of silver carp, bighead carp,grass carp and black carp in the niddle and lower stream of Changiiang miver, the biochenucak genetic vacation of four species sampled from Swan Oxbow, Hanyang, Ruichang and Anqing River sections of Changjiang River were analysed LKB horizontal acrylamide gel electrophoresis.
In mineral medium(MM) and with acryl-amide as exclusive carbohydrate, shaking - cultured at 30℃ and 108r/rmin in rotary vibrator for days, acrylamide degrad-ing strains of DAW0display relatively high degrading ability with 45. 01%.
Crosslinkable acrylic polymer emulsion was obtained by adding acrylic polymer emulsion incorporating diacetone acrylamide (DAAM).
表明能改变AaH -1 的 pH 环境、构象或使之变性的因素都能使它的萤光强度和 出血 活性同时发生相应的改变。
The fluorescence of AaH-1 is quenched by I ~ -, acrylamide and N-bromosuccini-mide (NBS).
Absorbent resin JT-1 is synthesized by using structural strengthening agent and acrylamide.
The most specific visualisation method is the localization of particular enzymes within an acrylamide gel.
