Talk:List of desiccants. Phosphorus pentoxide is often used in desiccators and in gas drying columns. Solvents are distilled from calcium hydride, sodium, potassium, sodium-potassium alloy, sodium-benzophenone. Magnesium is used to dry methanol. Sulfuric acid is used in a Drechsler bottle for drying gases at low pressure.
So often when the word "desiccant" is used, people automatically think of the three main types of desiccants: Indicating Silica Gel, Molecular Sieve, and Clay desiccant. Those who have heard of other desiccants, like Calcium Oxide, Montmorillonite Clay and Calcium Sulfide, may or may not have a clear understanding of those desiccant types.
Anti-desiccant sprays help living plants, particularly evergreens, retain water during freezing weather or summer droughts or following transplantation. Anti-desiccants can also preserve needles on Christmas trees and wreaths. Many natural anti-desiccant sprays contain pine oil, a natural, nontoxic .
Anti-desiccants. Anti-desiccants, such as Wilt-Pruf, are used on broadleaved evergreens to reduce winter drying or desiccation. Most anti-desiccants contain a waxy formulation which prevents water loss from leaves. Winter thaws may breakdown the compounds, necessitating re- application. Avoid using anti-desiccants on the under side of leaves.
A desiccant is a substance that absorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture. List of desiccants: Activated alumina; Aerogel; Benzophenone; Bentonite clay; Calcium chloride; Calcium oxide; Calcium sulfate (Drierite) Cobalt(II) chloride; Copper(II) sulfate; Lithium chloride
Protecting Evergreens in the Winter Q&A Winter desiccation injury is a common, unfortunate problem for landscape evergreens like Arborvitae and Juniper. Below are some questions and answers about managing desiccation injury with anti-desiccant sprays:
How to Use Anti-Desiccants. Anti-dessicants are most often used on: Broadleaf evergreens such as azalea, boxwood, holly, and rhododendron. Conifers such as arborvitae, cedar, cypress, juniper, and pine. Tender stems such as rose canes and hydrangea stems.
A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.Commonly encountered pre-packaged desiccants are solids that absorb water.Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such as chemical bonding of water molecules.
