Main functions and functions of medical grade methyl salicylate Methyl o-hydroxybenzoate, also known as methyl salicylate and methyl salicylate, is an organic compound with the chemical formula C8H8O3, a colorless to pale yellow transparent Liquid, with a strong aroma of wintergreen oil
.
Natural products exist in essential oils such as stagwort oil, wintergreen oil, birch oil, green tea seed oil, clove oil, qian tree oil, tuberose oil, small dang medicated oil, camellia oil, ylang ylang oil and cherry, In apple and strawberry juice
.
Slightly soluble in water, soluble in common organic solvents such as ethanol, chloroform and acetic acid
.
It is easy to change color when exposed to the air
.
It is mainly used in the formulation of daily chemical essences, mainly for the preparation of ylang-ylang, tuberose, succulent, acacia, fuqi, saffron orchid, etc.
, but its most common use is to add fragrance to toothpaste
.
1.
Collect the branches and leaves of the rhododendron plant Baizhumu (commonly known as holly) tree, and extract the wintergreen oil by steam distillation
.
The holly branches and leaves are chopped and soaked in steam distilled water vapor, and the oil and water are separated from wintergreen oil
.
Fractional distillation under reduced pressure collects the middle distillate free of water and acid
.
2.
Add salicylic acid into the reaction kettle, add excess methanol, add catalyst sulfuric acid under stirring, and heat to react
.
After completion of the reaction, wash with water until neutral
.
Distillation is carried out again, firstly, methanol and residual water are distilled off at atmospheric pressure, and then the fractions can be collected by distillation under reduced pressure
.
3.
Separating methyl salicylate from natural essential oils by fractional distillation
