Gluconic acid Specification

The Gluconic acid, with the CAS registry number 526-95-4 and EINECS registry number 208-401-4, has the systematic name of D-gluconic acid. It is a kind of clear yellow to brownish-yellow solution, and belongs to the product categories: Biochemistry; Glucose; Sugar Acids; Sugars; Dextrins、Sugar & Carbohydrates. Gluconic acid occurs naturally in fruit, honey, kombucha tea, and wine. And the molecular formula of this chemical is C6H12O7.

The physical properties of Gluconic acid are as following: (1)ACD/LogP: -3.18; (2)# of Rule of 5 Violations: 1; (3)ACD/LogD (pH 5.5): -5.88; (4)ACD/LogD (pH 7.4): -6.87; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 7; (10)#H bond donors: 6; (11)#Freely Rotating Bonds: 10; (12)Polar Surface Area: 72.45 Å2; (13)Index of Refraction: 1.616; (14)Molar Refractivity: 38.91 cm3; (15)Molar Volume: 111.2 cm3; (16)Polarizability: 15.42×10-24cm3; (17)Surface Tension: 116.9 dyne/cm; (18)Density: 1.763 g/cm3; (19)Flash Point: 375.2 °C; (20)Enthalpy of Vaporization: 113.2 kJ/mol; (21)Boiling Point: 673.6 °C at 760 mmHg; (22)Vapour Pressure: 4.95E-21 mmHg at 25°C. 

Preparation and uses of Gluconic acid: It can be prepared by 3 ways. (1)It can be obtained by the decomposition of calcium gluconate or sodium gluconate with sulfuric acid or oxalic acid; (2) It is obtained by the electrolytic oxidation of glucose in the alkaline solution. (3)It can be obtained by the fermentation of glucose. What's more, it is used as acidity regulators. And it is also used in cleaning products where it dissolves mineral deposits especially in alkaline solution.

You should be cautious while dealing with this chemical. It irritates eyes, respiratory system and skin, and it may cause burns. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).

You can still convert the following datas into molecular structure:
