Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 527-07-1, formula is C6H11NaO7, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Recommanded Product: Sodium Gluconate
Chen, Lei;Jiang, LinHua;Chu, Hongqiang;Xu, Peng;Jin, WeiZhun;Chen, Chen;Zhi, FangFang;Ben, Xunqin research published 《 Effect of retarder on hydration properties of light-burned magnesia》, the research content is summarized as follows. Light-burned magnesia (LBM) is a common expansive agent to compensate for the thermal shrinkage of mass concrete, and the expansive property of MgO mass concrete is affected by the hydration behavior of LBM. Besides, retarder is usually added to extend the setting time of mass concrete in hot climate construction. Retarder affects hydration of cement and LBM at the same time. However, little is known about the effect of retarder on the hydration of LBM expansive agent. This paper investigated the effects of four retarders (citric acid, sodium gluconate, tartaric acid and calcium sulfate) on the hydration behavior of LBM expansive agent. Setting time, hydration heat, hydration degree and compressive strength were employed to characterize the hydration process of LBM with various retarders. Moreover, the composition of the product was quant. and qual. analyzed by XRD and TG, and the morphol. of the product was analyzed by SEM. The results showed that retarders mainly affected the hydration behavior in the early age of LBM. Citric acid inhibited the hydration of LBM, but improved the compressive strength by forming flower-like Mg(OH)2 crystal. Tartaric acid inhibited the hydration of LBM, and produced products with poor crystallinity. Furthermore, sodium gluconate significantly prolonged the setting time of LBM and obtained complete brucite products. Besides, calcium sulfate accelerated the hydration of LBM at 1.0 water/LBM ratio, but inhibited the hydration at 0.45 water/LBM ratio. Finding from this study may provide new insights into the design and comparison of exptl. studies on the expansive property of MgO mass concrete affected by retarders.
Recommanded Product: Sodium Gluconate, Sodium Gluconate is the sodium salt of gluconic acid with chelating property. Sodium gluconate chelates and forms stable complexes with various ions, preventing them from engaging in chemical reactions.
Sodium gluconate is an organic sodium salt having D-gluconate as the counterion. It has a role as a chelator. It contains a D-gluconate.
D-Gluconic acid sodium salt is a glycol ether that is used as an injection solution. It has been shown to have antibacterial efficacy against wild-type strains of bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The in vitro antimicrobial action of D-gluconic acid sodium salt was found to be due to its ability to inhibit bacterial growth by interfering with the synthesis of DNA. D-gluconic acid sodium salt also has been shown to have antihypertensive effects in rats through the inhibition of angiotensin II type 1 receptor (AT1) signaling pathway and erythrocyte proliferation. This drug also has been shown to bind benzalkonium chloride and x-ray diffraction data show that it is crystalline in nature. The analytical method for determining the concentration of D-gluconic acid sodium salt is by electrochemical impedance, 527-07-1.
