Show ACID FOR MAKING SUGAR fl Curious Process Which Has Met With Sonic Success In France A very novel method of making sugar sug-ar has been patented in France by M Pellegrini Sugar is chemically a compound com-pound of carbon oxygen and hydrogen in such proportions that if carbonic acid water and certain kinds of illuminating illumi-nating gas could be persuaded to unite in the proper quantities the composition of sugar would be exactly imitated Hitherto no one has been able to make i sugar by mixing water with two kinds j of gas but M Pellegrini claims to have succeeded The apparatus he uses consists con-sists of a large block of pumico stone cleansed by soaking first in sulphuric acid and then in water which is set in an iron box plated with nickel inside The length of the box is three times that of tho pumice stone block which is tightly fitted in the middle and pipes 4 are arranged to convey tho ingredients to the empty ends of the box as required requir-ed Two of them enter from the sides and serve to bring carbonic acid and i hydrocarbon gas while another pipe from above branches so as to reach both empty portions of the box and conveys Btearn All tho pipes are fitted with valve and pressure gauges Another pipe at tho bottom of the box serves as an ouUet At first this Ipipe is closed as is also tho steam pip from above and carbonic acid is forced into one end of tho box while ethylene gas is forced into tho other under equal pressure and in equal volumes A few minutes later tho steam valve above is opened and the steam forced in under the same pressure As the gases unite the pressure falls so that the supply of each must be kept constant At tho end of half an hour tho supply of gas is shutoff shut-off the outlet pipe is opened and one of tho chambers is found to be filled with sirup containing 25 per cent of sugar Tho sirup is drawn off for refining and as soon as tho apparatus is cool it is ready for a fresh charge Tho cthy leno gas can be obtained by roasting rosin or grease but LI Pellegrinis patent pat-ent covers other hydrocarbons such as petroleum products The explanation is that tho threo gases are condensed in tho pores of the pumice stone and there ttnite American Architect |
