Methods of Manufacturing

Preparation of a composition comprising pure 1, 3:2, 4-di(3, 4-dimethylbenzylidene)-D-sorbitol and organosilane treated fume silica powders (0060) A 10 L four-necked cylindrical shaped reaction flask equipped with a thermometer, a nitrogen inlet, and a mechanical stirrer was charged with D-sorbitol (400 g, 2.20 moles), camphorsulfonic acid (12 g), 3, 4-dimethyl-benzaldehyde (530 g, 3.95 moles) and methanol (4250 g), and then reacted at room temperature for 48 hours, so as to form a first reaction mixture. (0061) After neutralizing the first reaction mixture to pH 8, VenPure™, 20 grams of sodium borohydride solution having 12percent of NaBHExample- 13; The choline chloride (1.4 gm) and methanesulfonicacid (MSA) (0.96 gms) were added to methanol (30 ml) and mixed well to prepare the ionic fluid. 3, 4 dimethyl benzaldehyde (1.5 ml) and sorbitol (1.5 gm) were added to the ionic fluid and stirred to initiate the reaction at 26°C. The thick solid mass formed after few minutes of starting the reaction and the reaction was continued for 8 hrs. The solid product was filtered and washed with 100 ml diethylether. The white solid product was dried in oven at 95°C for 2 hrs followed by air dried for 4 hrs for measuring the yield. The yield and purity were found to be 80percent and 99.8percent respectively.General procedure: [0095] The choline chloride (1.4 gm) and methanesulfonicacid (MSA) (0.96 gms) were added to methanol (30 ml) and mixed well to prepare the ionic fluid. 3, 4 dimethyl benzaldehyde (1.5 ml) and sorbitol (1.5 gm) were added to the ionic fluid and stirred to initiate the reaction at 26° C. The thick solid mass formed after few minutes of starting the reaction and the reaction was continued for 8 hrs. The solid product was filtered and washed with 100 ml diethylether. The white solid product was dried in oven at 95° C. for 2 hrs followed by air dried for 4 hrs for measuring the yield. The yield and purity were found to be 80percent and 99.8percent respectively.Example: 1; Toluene-4-sulphonic acid monohydrate (PTSA), a hydrogen donor (2gms) was mixed with sodium chloride (0.6 gms) in equal mole ratio and 30 ml methanol was added to the salt mixture and stirred well to prepare ionic fluid. The ionic fluid obtained was used for carrying out the dehydration reaction at 26°C. 3, 4 dimethyl benzaldehyde and sorbitol in 2: 1 mole ratio were added to the ionic compound and stirred to initiate the reaction. The solid mass formed within few minutes of starting the reaction. The stirring speed was increased to keep the mass in suspension condition and reaction was continued for 5 hrs. The solid product was filtered to obtain mother liquor and a white solid mass. The white solid mass was washed with 120 ml methanol. The white solid product was dried in oven at 95°C for 2 hrs followed by air dried for 4 hrs for measuring the yield. The yield was found to be 77percent.EXAMPLE 5
