Sodium formate Specification

The Sodium formate, with the CAS registry number 141-53-7,is also known as Thionyl dichloride. It belongs to the product categories of Salachlor; Formic acid sodium salt.This chemical's molecular formula is CHNaO2 and molecular weight is 68.01. What's more,Its systematic name is Sodium formate.It is white crystals,which is stable,incompatible with strong oxidizing agents,strong acids,protect from moisture.Its storage temperature is 2-8°C.The Sodium formate is irritating to eyes, respiratory system and skin.When you use it ,wear suitable protective clothing, gloves and eye/face protection.In case of contact with eyes, rinse immediately with plenty of water and seek medical advice .

Physical properties about Sodium formate are:
(1)ACD/LogP:  -0.54; (2)# of Rule of 5 Violations:  0; (3)ACD/LogD (pH 5.5):  -2.30; (4)ACD/LogD (pH 7.4):  -3.94; (5)ACD/BCF (pH 5.5):  1.00; (6)ACD/BCF (pH 7.4):  1.00; (7)ACD/KOC (pH 5.5):  1.00; (8)ACD/KOC (pH 7.4):  1.00; (9)#H bond acceptors:  2; (10)#H bond donors:  1; (11)#Freely Rotating Bonds:  0; (12)Flash Point:  29.9 °C; (13)Enthalpy of Vaporization:  22.69 kJ/mol; (14)Boiling Point:  100.6 °C at 760 mmHg; (15)Vapour Pressure:  36.5 mmHg at 25°C.

You can still convert the following datas into molecular structure:
(1)SMILES:[Na+].[O-]C=O;
(2)Std. InChI:InChI=1S/CH2O2.Na/c2-1-3;/h1H,(H,2,3);/q;+1/p-1;
(3)Std. InChIKey:HLBBKKJFGFRGMU-UHFFFAOYSA-M.

Production of Sodium formate:
Reacting chloroform with an alcoholic solution of sodium hydroxide produces sodium formate; neutralizeing formatic acid with sodium carbonate also produces Sodium formate. The formular is as following:
CHCl3 + 4NaOH → HCOONa + 3NaCl + 2H2O
by reacting sodium hydroxide with chloral hydrate:
2HCl3(OH)2 + NaOH → CHCl3 + HCOONa + H2O
The latter method is better than the former, since the low aqueous solubility of CHCl3 makes it easier to separate out from the sodium formate solution than the soluble NaCl would be by fractional crystallization.
The commercial way to produce sodium formate is to bsorbing carbon monoxide under pressure in solid sodium hydroxide at 160 °C, showing below:
CO + NaOH → HCOONa
