Title: Bis beta-hydroxyethyl terephthalate purification
Inventor: YATARO ICHIKAWA
IPC: C07C69/82
Filed: 1968-12-30
Abstract: Crude bis(beta-hydroxyethyl) terephthalate (BHET) is purified by (1) dissolving in a hot aromatic solvent to a concentration higher than the saturation solubility of the ester at the apparat melting point (Tm) of BHET in the solvent; the solvent is at a temp. higher than Tm, (2) cooling the solution very rapidly to below Tm so that the precipitate is not granular or lumpy, and (3) separating off the solid. Impurities are removed which retard the polycondensation of the ester and discolour the polymer and lower its melting point. Recrystallisation processes using other solvents, e.g. water (US. 3,062,862) and polar organic solvent (US. 3,120,560 and 3,268,575) are complicated by the high solubility of the ester in these solvents at ambient temp.

The apparatus is controlled by a control unit that receives a position signal from the position locating unit. The control unit compares the signal with the data in the mapping unit and applies a signal to the planting unit to cause or otherwise a planting operation to occur at its located position in dependence upon the data that defines the pattern. The apparatus can make multiple passes over an area of land to plant several plants to give a desired visual effect. Alternative embodiments of the invention can plant multiple plant varieties in one pass. A programming unit enables a user to design a pattern and store data to create it in the mapping unit.
