What is the boiling point of Product T58300, Triethanolamine?
The boiling point is not determined by Sigma-Aldrich, but is reported to be 190-193°C at a reduced pressure of 5mm Hg.
Product T58300, Triethanolamine, was received as a solid and it usually arrives as a liquid. Is the product still acceptable?
Yes, the product is still acceptable. Triethanolamine has a melting point of 17.9-21°C, which is near room temperature. The item ships under ambient conditions. As a result, it may arrive as a solid when exposed to cold temperatures (especially during the winter months). Gentle heating in a warm water bath will easily convert the material back into its expected viscous liquid appearance.
What kind of gloves would be recommended when working with Product T58300, Triethanolamine?
When working with the material, we would recommend neoprene, nitrile or butyl gloves. For example, the Best® butyl, ChemMaster™ or N-DEX®  gloves listed at the following link could be used with triethanolamine. http://www.sigmaaldrich.com/catalog/search/TablePage/17189752
