In view of the fact that a methyl vinyl ether, which is useful as a starting material for the synthesis of tetraalkoxypropane useful as a skeleton-forming agent having a high reactivity usable as a starting material, etc. for a pharmaceutical and agrochemical intermediates such as a pyrazole derivative or pyrimidine derivative, particularly 1,1,3,3-tetramethoxypropane, is in a gaseous state and difficult to use for industrial production, tetraalkoxypropane useful as a skeleton-forming agent for a pharmaceutical and agrochemical intermediate such as a pyrazole derivative or pyrimidine derivative is easily produced on an industrial scale by using the industrially useable propoxyvinyl ether, as a starting material, without using a gaseous state methyl vinyl ether.

The present invention relates to the use of at least one compound of formula (I) R—(OCH
2
)n—OR′ in which R and R′, identical or different, represent a linear or branched alkyl radical comprising 1 to 5 carbon atoms and n is an index with a value comprised between 1 and 8, and/or at least one dialdehyde acetal type compound for the preservation of the human or animal body and/or the embalming of dead bodies.
It also relates to a composition comprising same and a process for preserving a human or animal body and/or embalming a dead body comprising the administration of the composition to the dead body in particular by injection, perfusion, immersion or topical application.
