Glycerine is a colorless, odourless, viscous liquid. It is sweet-tasting and of low toxicity. Glycerine has three hydrophilic hydroxyl groups that are responsible for its solubility in water and its hygroscopic nature.
Applications
In organic synthesis, glycerol is used as a readily available prochiral building block.
Glycerin can also serve as a substitute for petroleum based products. Glycerin derived propylene glycol are substitutes for petroleum-based propylene.
Research laboratory usage
Glycerol is a common component of solvents for enzymatic reagents stored at temperatures below zero degrees Celsius due to the depression of the freezing temperature of solutions with high concentrations of glycerol. It is also dissolved in water to reduce damage by ice crystals to laboratory organisms that are stored in frozen solutions, such as bacteria, nematodes, and fruit flies. Samples are loaded into agarose gel electrophoresis mixed in loading buffers that mainly consist of glycerol; when the sample is injected into wells, the glycerol causes the solution to sink through the running buffer to the bottom of the well.
Potential uses
Some potential uses for glycerol include the following:
- Glycerine acetate (as a potential fuel additive)
- Compost additive
- For Tincture extraction and preservation of Essential oils and chemicals from herbs.
- Citric acid production
- Conversion to propylene glycol
- Conversion to ethanol
- Glycerol may be used as antifreeze for plants, if mixed with water in a 10% solution. It is believed to be effective at temperatures near –18C
- Glycerin may serve as a source of energy used in waste water treatment plant digesters
Preserving Tree Branches
- Cut branches when color begins to change, before the leaves are completely tinted. (Fully turned leaves are too dry and brittle.) Beech, oak, wild apple, mountain ash and copper beech are well suited for this method of preservation.
- Use a solution of 2 parts water to 1 part glycerine. The amount needed depends on the size of the branches. (The stems must be in liquid to a depth of 3 to 4 inches.)
- Trim off any small twigs at the bottom of the branch. Slit the bottom of each stem with a sharp knife to 3 or so inches.
- Next, bruise the stalks with a hammer.
- Arrange the branches in a container of the water/glycerine mixture and place in a cool room for a week to ten days. The leaves will last for years! Makes great centerpieces and displays.
