Phthalic Anhydride (PA) White scaly or Crystalline powder, Molecular formula C8H403, Molecular weight 148.12, Melting point 131.1l , Boiling point 284.5 , Flash point 151 (close), 165 (open), Spontaneous combustion point 584 , Density (Solid) 1.527g / cm3, insoluble in water, soluble in water, alcohol, ether, benzene and most organic solvents. Phthalic anhydride is a cyclic anhydride, is an important chemical raw material, especially for plasticizer manufacturing. Dibutyl phthalate, Dioctyl phthalate are important plasticizers. Phthalic anhydride and polyols (such as glycerol, pentaerythritol) can generate polyarylate resin in condensation way, used in paint industry; if an unsaturated acid with ethylene glycol happening condensation, the resulting chemicals is unsaturated polyester resin, for the manufacturing of insulating paint and glass fiber reinforced plastics . Phthalic anhydride is a raw material of benzoic acid, terephthalic acid, also used in pharmaceutical synthesis.

Adipic acidProperties Adipic acid, commonly known as fatty acid, is also called hexane dicarboxylic acid, molecular formula for C6H10O4, molecular weight is 146.14.Ar room temperature it is monoclinic crystal.Melting point 152 �¢??, boiling point 337.5 �¢??, the relative density is 1.366. It is soluble in ethanol, ethyl ether, acetone, etc., product of adipic acid is white, odorless, crystalline solid.It has good stability in air, it is slightly soluble in water, easy soluble in alcohol, ether and most organic solvents, it has connectivity of aliphatic dibasic acid, including salt reaction, esterification and amidation reaction, etc., it can be condensed into a polymer with diamine. Applications:Adipic acid can be carried on condensation reaction with polyfunctional compounds, such as adipic amine. In industry, using adipic acid with hexamethylenediamine soho reaction produce nylon 66 salt (AH salt for short), by further polycondensation of nylon 66 salt, can get nylon 66 resin. In addition, reacting with alcohols, adipic acid can produce adipate, used as plasticizer, synthetic lubricant and polyester polyols and other products, can be used for all kinds of food and drink sour agent. Due to no n-deliquescence, adipic acid is especially suitable for dry food, can be stored for a long time.
Product name High Effective Pure Glucose Powder, Additives In Blood Tubes CASã??50-99-7 Appearance Colorless Transparent Powder MOQ 1kg Usage Moisture Molecular Formula CH2OH(CHOH)4CHO+2Ag(NH3)2OH Properties White Powder Glucose, organic compound, molecular formula C6H12O6. It is the most widely distributed and most important monosaccharide in nature. It is a polyhydroxy aldehyde. Pure glucose is colorless crystal, sweet but not as sweet as sucrose (can not taste sweet), soluble in water, slightly soluble in ethanol, insoluble in ether. The natural glucose aqueous solution is optically responsive to the right, so it belongs to "dextrose". Glucose plays an important role in the biological field. It is the energy source of living cells and the metabolic intermediate, the main energy-generating substance of living things. Plants produce glucose through photosynthesis. It is widely used in the field of candy manufacturing and medicine. Chemical properties It is the most widely distributed monosaccharide in nature. Glucose contains five hydroxyl groups, one aldehyde group, having the properties of a polyol and an aldehyde. It is easily decomposed by heating under alkaline conditions. It should be kept in a sealed state. It is quickly absorbed after oral administration and is used by tissues after entering the human body. After 1kg of glucose is completely oxidized by the human body, 2870KJ of energy is released. Some of this energy is converted into 30 or 32mol of ATP. The rest of the energy is released as heat to maintain body temperature. It can also be converted into glycogen or fat by liver or muscle. (1) The aldehyde group in the molecule is reducible and can react with silver ammonia solution: CH2OH(CHOH)4CHO+2Ag(NH3)2OH-water bath heatingCH2OH(CHOH)4COONH4+2Ag+3NH3+H2O, oxidized Into ammonium gluconate. (2) The aldehyde group can also be reduced to hexahexol. (3) There are a plurality of hydroxyl groups in the molecule, which can be esterified with an acid. (4) Glucose undergoes an oxidation reaction in the living body, releasing heat (C6H12O6 + 6O2 (oxygen) + 6H2O = = 6CO2 + 12H2O + energy). (5) Glucose can be obtained by hydrolysis of starch under the action of enzyme or sulfuric acid. (6) Plant photosynthesis: 6CO2+6H2O (chlorophyll, sunlight catalysis) - C6H12O6+6O2. (7) Reaction equation between glucose and new copper hydroxide: CH2OH(CHOH)4CHO+2Cu(OH)2-heated->CH2OH(CHOH)4COOH+Cu2O+2H2O. (8) Glucose is decomposed into water and carbon dioxide under certain conditions. (9) Hydrolysis of maltose: C12H22O11+H2O-catalyst2CH2OH(CHOH)4CHO (10) Starch and cellulose hydrolysis: (C6H10O5)n+nH2O-catalystnCH2OH(CHOH)4CHO
