General description

Tetrapropylammonium hydroxide, a quaternary ammonium compound, is mainly used as a structure directing agent for the preparation of molecular sieves[1] and zeolites.[2]

Application

  • Density Measurement of Aqueous solution of Tetrapropylammonium Hydroxide at different Temperatures and Concentrations: Data and Correlation: This study investigates the densities of aqueous Tetrapropylammonium hydroxide solutions across various temperatures and concentrations (SB Sufian, AM Shariff, 2018).
  • Tetrapropylammonium Hydroxide as a Zinc Dendrite Growth Suppressor for Rechargeable Aqueous Battery: This research explores the use of Tetrapropylammonium hydroxide as an electrolyte additive to improve the performance of aqueous Zn batteries (I Kurmanbayeva, L Rakhymbay, 2020).
  • Measurement and correlation of the physical properties of aqueous solutions of ammonium based ionic liquids: This paper examines the physical properties of various ammonium-based ionic liquids, including Tetrapropylammonium hydroxide (NA Kartikawati et al., 2018).
  • Tetrapropylammonium hydroxide treatment of aged dry gel to make hierarchical TS-1 zeolites for catalysis: This study focuses on the synthesis of hierarchical TS-1 zeolites using Tetrapropylammonium hydroxide treatment under hydrothermal conditions (Z Yang et al., 2023).
  • Effect of concentration of tetrapropylammonium hydroxide on silica suspensions for making spin-on porous low dielectric constant films: This article investigates the impact of different concentrations of Tetrapropylammonium hydroxide on silica suspensions used in the production of spin-on porous films (TY Li et al., 2014).

Questions

1–2 of 2 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
