摘要:The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

权利人:EASTMAN KODAK CO
摘要:A PROCESS FOR THE SYNTHESIS OF PHENYL ESTERS DIRECTLY FROM THE CORRESPONDING PHENOLS AND CARBOXYLIC ACIDS WHICH COMPRISES CONTACTING A PHENOLIC COMPOUND HAVING AT LEAST ONE HYDROGEN ATOM ADJACENT THE ACTIVE HYDROXYL GROUP WITH A CARBOXYLIC ACID COMPOUND CONTAINING AT LEAST ONE ACTIVE CARBOXYLIC GROUP IN THE PRESENCE OF A CATALYTIC AMOUNT OF A BORATE-SULFURIC ACID CATALYST COMPLEX. THE PROCESS IS CARRIED OUT IN A SINGLE STAGE REACTOR WHICH MAY BE OPERATED AT FROM 75*C. TO 285*C. UNDER ATMOSPHERIC, SUBATMOSPHERIC OR SUPERATMOSPHERIC PRESSURE. IF DESIRABLE, A SOLVENT CAN BE EMPLOYED.

摘要:The present invention relates to a composition for maintaining efficacy of a filler for a long period of time by containing collagen as an active ingredient. The composition according to the present invention is useful since the composition can promote the synthesis of hyaluronic acid and inhibit activity of hyaluronidase, thereby maintaining the efficacy of a hyaluronic acid filler for a longer period of time. Therefore, even with less number of times of filler injection, the efficacy of the filler can be maintained and skin irritation can be also reduced.
