ft., former Hercules/PFW facility in Middletown, NY; Fleurchem produces a full range of natural isolates, synthetic chemicals & specialities, essential oils and flavors.

Another method of producing bio-based propene is via syngas and propan-1-ol. Synthesis gas (carbon monoxide and hydrogen) is used to convert bioethanol to propan-1-ol (Figure 3, route 4):


Synthesis of copoly(ethylene terephthalate/imide)s and …


Any solid biomass including for example agricultural, city and industrial waste can be used to make synthesis gas using techniques similar to its production from . More recent developments includes a plant in the Netherlands, which is using liquid propane-1,2,3-triol (glycerol), a by-product from the production of , from animal fats and vegetable oils.

Postcondensation in the solid phase, 20°-30°C below Tm, was most effective after short melt polymerization times.AB - The synthesis of poly(ester amide) copolymers (PBTA) based on poly(butylene terephthalate) (PBT) and nylon-4,T with the diamide of butanediamine and dimethyl terephthelate (N,N′-bis(p-carbomethoxybenzoyl)butanediamine) has been carried out.

Synthesis gas formed from gasification of biomass can be converted into  (Figure 2, route 7).

KalamaTMBenzyl alcohol is used as an intermediate in the synthesis of polypeptides and is used extensively as a non-reactive diluent in epoxy resin coatings, where it reduces the viscosity and raises product flexibility.

Glass Transition Temperatures of Amorphous Polymers in Kelvin

Polyesters are long chain synthetic polymers that have ester linkages

Synthesis gas is converted into a hydrocarbon wax (a mixture of long-chain alkanes) by heating it and passing the vapour over a cobalt catalyst (the Fischer-Tropsch process) (Figure 2, route 5). The (SMDS) is a modern development of this process. The hydrocarbon waxes are subsequently catalytically cracked with excess hydrogen () (Figure 2, route 9) to form smaller alkanes, for example:

Another way to produce propene is via methanol (produced from biomass via synthesis gas), which is an example of the MTO (Methanol To Olefins) process. (Olefin is the older name for the homologous series, alkenes). Methanol can be converted into high purity ethene and propene via dimethyl ether (Figure 3, routes 10 and 9). Methanol vapour is passed over alumina at ca 600 K. An equilibrium mixture of methanol, dimethyl ether and steam is produced, containing about 25% methanol:
