一般描述

缩水甘油基三甲基氯化铵（GTMAC）是一种阳离子化剂，通常用于淀粉改性。[1]

应用

缩水甘油基三甲基氯化铵可用作衍生剂，与壳聚糖反应合成N-(2-羟丙基)-3-三甲基氯化铵壳聚糖（HTCC），一种水溶性壳聚糖衍生物。HTCC可与银纳米颗粒形成纳米复合膜，该膜具有良好的抗菌特性和光透明性。[2]阳离子淀粉还可通过用GTMAC衍生淀粉来制备。[3]

注意

储存过程中会水解（20℃下，约3.5％/月）

The electrospinning PAN nanofiber membrane (P-CN) was hydrolysed to convert carboxylic groups as reaction sites and covalently graft chitosan molecule. The chitosan derivatives with quaternary ammonium groups exerted greater efficiency against bacteria as compared to pure chitosan. Hence, the chitosan

An efficient and effective process for the production of high-performance anion exchange membranes (AEMs) is necessary for the commercial application of fuel cells. Therefore, in this study, quaternized poly vinylbenzyl chloride (QVBC) and polysulfone were composited with glycidyltrimethylammonium-chloride-quaternized chitosan (QCS)

Questions

1–4 of 4 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. From this information “Caution hydrolysis on storage (approx. 3.5%/month at 20°C)”  If I keep in storage -18 °C it’s can keep product from approx.? Or reduce some loss?

    1 answer

    1. The recommended storage temperature for the product is 2-8 °C. The retest period for this item is approximately one year from the quality release date when stored in these conditions. There is no stability information available regarding storage at -18°C.
