In , glycerol is used as a readily available building block. Even if glycerol with no substitutions is symmetrical, and carbon atoms 1 and 3 are exchangeable, once one of them forms an ester or ether bond, the two are no longer exchangeable. Further bond formation and may lead to products substituted solely at the third carbon; due to such circumstances, to maintain both full description and conformance to the chemistry naming rules (which require carbon counting to minimize ordinal numbers of substituents), the carbons are named -1, -2, and -3, with "sn" standing for "sterospecifical numbering".

Glycerol is a component of glycerol , which is made from , glycerol, sodium castorate (from ), , , , and water. Sometimes one adds , or for . This kind of soap is used by people with sensitive, easily-irritated because it prevents skin dryness with its properties. It draws moisture up through skin layers and slows or prevents excessive drying and evaporation. It is possible to make glycerol soap at home.
Renewable raw materials derived from biomass are regarded as the basis for the majority of petrochemical processes in the future. The advantage of renewable raw materials is the possibility of independence of some sections of the economy from fossil fuels. Up till now, only the technologies that have led to the introduction of products in demand on a given market or those with a strong legislative backing have been developed. This work is an attempt to evaluate the possibility of developing a new technology for the synthesis of acrylic monomers based on the renewable raw materials in response to the dynamic rise in Polish market demand for acrylic monomers, which is being currently resolved by import. In the theoretical part of the work, the main routes for the synthesis of acrylic monomers based on non-renewable fossil fuels have been described and compared to reactions based on renewable raw materials, especially those available locally. In the experimental part the results of the synthesis of acrolein from glycerol, i.e. the first stage of the process of synthesis of the production of acrylic monomers based on renewable raw materials, have been presented. The conversion of glycerol was performed in the gaseous phase over a series of industrial aluminosilicate catalysts. The influence of selected parameters on the activity of the system in the tested reactions was determined. By considering the obtained results in relation to those reported in the literature it can be concluded that a potential possibility exists in obtaining acrylic monomers on the industrial scale from renewable raw materials. Large scale tests are still required to be performed in order to come to a final evaluation and introduction of the developed technology.
