一般說明

硫酸氢钾是一种无机钾盐。它在从300加热到700°C时会转变为熔融形式,并已通过拉曼光谱对该转变过程中发生的反应进行了研究。[1]它的电导率值已被评估(T = 0-700C,压力 = 最高4000bars)。[2]
硫酸氢钾是一种水溶性无机盐,主要用作防腐剂、助焊剂,也用于制造肥料。[3]

應用

硫酸氢钾可被用于:
  • 作为由羟基苯甲酸和丁醇制备对羟基苯甲酸丁酯的催化剂。[4]
  • 作为在乙二醇中通过Biginelli反应合成3,4-二氢嘧啶-2(1H)-酮衍生物的促进剂。[5]
  • 作为酸催化剂用于通过反应蒸馏由乙醇和丁醇合成乙基丁醚(ETBE)。[6]
  • 作为由酒石酸合成丙酮酸的脱水剂。[7]
硫酸氢钾(硫酸氢钾)可作为催化剂用于对羟基苯甲酸丁酯[4]和肉桂酸甲酯的合成。[8]它也可用于通过重量分析法估算绿柱石中的铍。[9]

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
