Product Production：
Glycerol ester of wood rosin is produced by the esterification from wood rosin and glycerol.
A solid resin extracted from aged pine stumps, it can be refined by removing volatile terpene fractions and impurities before the esterification with glycerol.
It is the general name of various rosins esterified with glycerol, e.g: glycerol ester of gum rosin, glycerol ester of tall oil rosin, glycerol ester of partially hydrogenated gum or wood rosin and so on.
