Description

Patented Nov. 26, 1929 PATENT OFFICE WILLI SCHULTZE, OF HALLE-ON-THE-SAILE, GERMANY PROCESS TREATINGJPALLOEL 7 Ho Drawing. Application filed September 80, 1927, Serial No. 223,241, and in Germany October 11, 1926.
-si1lt hitherto obtained has not been satisfac- 10 (in some cases up to 90%). There are two steam or under vacuum or both, one can scptory however.
The invention is concerned with the same problem, resulting in the separation of the majority of the fatty acid'from the t-alloel ways of obtaining this result. One well known method consists in first of all distilling the talloel and thereupon subjecting the distillate to a further fractional distillation.
Applicants method which is described sub sequently is based on esterifying the talloel according to methods which merely effect an ters and unsaponifiable matter dissolved in benzene, the lower layer the soda soaps of the resin-acids in aqueous-alcoholic solution.
The fatty acid ester solution is washed out with H O or 50% alcohol after separation of the lower layer, then freed from benzene by distillation and now forms a yellow oil, which smells like olive oil.
By careful distillation, for instance, with arate the fatty acid esters from the unsaponifiable matter and thus obtain the esters absolutely pure.
-The alcohol is removed from the aqueousalcoholic resin soap solution by distillation, the remaining aqueoussoap solution is decomposed by diluted sulphuric acid whilst esterification of the fatty acids but not of the stirring with benzene. The extraction of esv resinic acids contained in the talloel. for instance the talloel is treated with alcohol and concentrated sulphuric acid; about 100 kg. talloel, 25 kg. alcohol and 4 kg. concentrated sulphuric acid of 66 B. The talloel esterified in this manner is then distilled in any known way. The term talloel which literally means pine oil is a liquid resin.
As a specific example, I mix 100 kilos of talloel with 25 kilos alcohol and 4 kilos sul-' phuric acid of 66 B and heat the mixture under a reflux for two hours. The reaction mixture is then left at rest until the sulphuric acid layer has separated out is a bottom layer. The sulphuric acid layer is drawn off and discarded.
The ester mixture is now mixed with such a quantity of aqueous caustic soda solution that ing the split off or separated alcohol. The
acids are separated from the soap by decomposition with dilute mineral acid.
According to the methods referredto it is possible to obtain from the talloel, fatty acids which contain such a small amount of resin acids, that they can befurther used indus-- trially, which was impossible according to methods employed hitherto owing to the detthe unesterified resin-acid and residue of sulrimental, Content 0f resinphuric acid are neutralized. The end or final pointof the neutralizatidn is ascertained by testing with an indicator, for instance, phenolphthalein. A slight excess of; caustic soda Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is should preferably be used. Th quantity of y The p ocess of eat ng ta loel to sepacid which considerably varies in talloel a alkali used depends on the. content of resifig onthe content of sulphuric acid.
Thecooled solution is then stirred thor oughly twice with benzene or, for instance,
with about 25% of the neutralized esterifying mixture. Two layers are formed. The
" arate the liquid fatty acid componentsthereupper layer contains the fatty acid ethyl es-- terification mixture.
2. The process of treating talloelto separate the liquid fatty acid components thereof from the resinic acid components thereof which comprises treating the talloel with a mixture of alcohol and sulphuric acid to esterify only the liquid fatty acids, and thenseparating the esterified fatty acids from the esterification mixture.
3. In the process of treating talloel to separate the liquid fatty acid components thereof from the resinic acid components thereof, the step which com rises su jecting the talloel to the action 0 an esterifying agent to esterify only the liquid fatty acid compo-v nents. 1
4. In the process of treating talloel to separate the liquid fatty acid components thereof from the resinic acid components thereof, the step which comprises subjecting the talloel to the action of an esterifyingmixture comprising alcohol and sulphuric acidto esterify only the fatty acid components.
5. The process of recovering the liquid I fatty acids occurring in talloel which comprises subjecting the talloel to the action of an esterifyin agent to esterify only the liquid fatty aci 5 contained therein, se arating the fatty acid esters so prepared mm the esterification mixture and then treating the esters with a hydrolytic agent to obtain the free fatty acids.
In testimony whereof I have signed my name to this'specificationt WILLI SCHULTZE.
