  Verfahren zur Herstellung von   Kunstprodukten.   
 EMI1.1 
 Es wurde nun gefunden, dass gewisse Ester von   Glyeerinäthern   ganz besonders als   Gelatinierungs-und   Weichmachungsmittel für Celluloseester und-äther oder Gemische von ihnen geeignet sind. Als Ester von   Glycerinäthern   im Sinne vorliegender Anmeldung kommen Äther von Glycerin in Frage, bei denen Glycerin mit einem weiteren   Molekül Glycerin   oder deren mehreren veräthert ist und diese Äther wenigstens an einer Hydroxylgruppe mit   Essigsäure   oder einer ihrer höheren Homologen bis zur Valeriansäure verestert sind.

   Diese Ester von Glyeerinäthern stellen viskose   Flüssigkeiten von hohem Siedepunkt vor,   die in Wasser   unlöslich,   geruchlos und farblos sind. Sie übertreffen die   bekannten   Glyzerinester ganz 
 EMI1.2 
 und ihrer   Widerstandsfähigkeit gegen   den Einfluss von Licht. 



   Beispiel. 



   100 Teile   acetonlösliche   Acetylcellulose werden   mit 30-50   Teilen Diglycerintetraacetat der Formel

 werden.

   Selbstverständlich können dabei die zu gewinnenden Kunstprodukte auf dem Wege ihrer Herstellung mit allen den in dieser Industrie gebräuchlichen Zusatzstoffen, wie Farbstoffen,   Füllmitteln   u. dgl., versetzt und den sonst üblichen Verarbeitungsmethoden unterworfen werden.

  Process for the production of artificial products.
 EMI1.1
 It has now been found that certain esters of glycerol ethers are particularly suitable as gelatinizing and plasticizing agents for cellulose esters and ethers or mixtures thereof. As esters of glycerine ethers in the sense of the present application, ethers of glycerine come into question in which glycerine is etherified with another molecule of glycerine or several and these ethers are esterified to valeric acid at least at one hydroxyl group with acetic acid or one of its higher homologues.

   These esters of glycerol ethers represent viscous liquids of high boiling point that are insoluble in water, odorless, and colorless. They completely surpass the known glycerol esters
 EMI1.2
 and their resistance to the influence of light.



   Example.



   100 parts of acetone-soluble acetyl cellulose are mixed with 30-50 parts of diglycerol tetraacetate of the formula
 EMI1.3
 with the addition of a mixture of acetone with a little alcohol and benzene to pla-
 EMI1.4
   Plasticizers for acetyl cellulose, nitrocellulose, other and mixed cellulose esters such as cellulose ethers, may be mentioned diglycerol triacetate of the formula

 will.

   It goes without saying that the synthetic products to be obtained can be produced with all the additives commonly used in this industry, such as dyes, fillers and the like. Like., be added and subjected to the usual processing methods.
