| titleOfInvention | PROCEDURE FOR OBTAINING 1-ARYLPROPANDIOL-1, 3-DIACILATES |
| abstract | OBTAINING OF 1,3-DIACILATO, 1-ARILPROPANDIOL, BY REACTION OF ARILOLEFINAS WITH CARBOXILIC ACIDS AND / OR THEIR ANHYDRIDS AND FORMALDEHYDES IN MOLAR PROPORTIONS FROM 1: 2 TO 10: 0.5 TO 2 IN THE PRESENCE OF AN ACID CATALYST, ADDED THE MIXTURE A 4-ARYL-DIOXANE-1,3 THAT PREVENTS PRECIPITATION, IN MOLAR PROPORTIONS OF 0.1 TO 1 MOL, ESPECIALLY OF 0.2 TO 0.4 MOLES OF 4-ARYL-DIOXANE-1.3 / MOL / ARILOLEFINA; BETWEEN 10J AND 50JC AT OVERPRESSURE OR VACUUM. OF THE ARYLOLEFINES THE STYRENE AND THE METHYL LYRENE ARE USED; OF THE ACIDS, THE ACETIC, PROPIONIC OR ISOBUTIRICO WITH ITS ANHYDRES, IN MOLAR PROPORTIONS OF 1: 3 TO 5. AS ACID CATALYSTS, THE CONCENTRATED SULFURIC ACID OR THE ION EXCHANGERS ARE USED. AS FORMALDEHYDE, MONOMER FORMALDEHYDE AND PARAMHORMALDEHYDE. REACTIONS CONCLUDE BETWEEN 2 AND 12 HOURS, WITH A SECONDARY REACTION BETWEEN 8 AND 48 HOURS, THE PERFORMANCE CAN BE INCREASED; AFTER THE CONVERSION, THE REACTION OBTAINED IS EVENTUALLY NEUTRALIZED; THE SUBSEQUENT TRANSFORMATION IS VERIFIED BY RECTIFICATION. OF GREAT INTEREST FOR OBTAINING ODORIFEROUS SUBSTANCES. |
