Styrax officinalis

Storax Probably from Styrax officinalis plants Moldenke and Moldenke (1952)... 

Benzoe resin (also known as benzoin) comes from Styrax spp. (Styraceae family). In the Sty rax genus the only species that occurs in the Mediterranean is Styrax officinalis, so this was probably the source of the resin in ancient times in that area. Benzoe mainly contains free cinnamic and benzoic acids, and their corresponding esters with cinnamyl, p-coumaryl and coniferyl alcohols. The amounts of these compounds are quite variable and depend on which species the resin was obtained from [129]. 

Polyvinyl benzene or styrene is the simplest Aromatic hydrocarbon which can be polymerised. Styrene was obtained by steam distillation of resin from the tree Styrax officinalis. In 1920s Staudinger gave the name styrene. Patent for polymerisation of styrene was taken out in 1911 by Matthews. 

Akgul and Anil have reported the isolation of the novel benzofuran, 4-[3"-(lc-methylbutanoyloxy)propyl]-2-methoxy-(3, 4 -methylenedioxyphenyl)-la,5b-dihydrobenzo-[3,4]-cyclobutaoxirene (Figure 18) from the hexane extract of the seeds of Styrax officinalis <2003P939>. 

St3rrene, Phenyl Ethylene.— The first of these hydrocarbons is known as st3rrene. It is obtained from storax a resin found in the plant, Styrax officinalis. It is also present in coal tar. It is related to, and also prepared from, cinnamic acid, an important acid to be considered later. Styrene is a liquid boiling at 140 . Its constitution is proven by its synthesis from benzene and ethylene when a mixture of the two compounds is passed through a red hot tube. 

Simon in 1839 named the distillate of Styrax officinalis a styrol. By 1845, the thermal polymerization of styrene as well as the thermal depolymerization of PS was known. In 1915, I. G. Farbenindustrie started commercial production of PS, Trolitul . Until the 1950s, PS was produced in small quantities - the resin was brittle, thermally unstable, with poor solvent and scratch resistance. The main use of styrene was in the manufacture of styrenics, viz., Buna-S, SBR, or ABS.
