996-31-6 Usage

Description

Potassium lactate is a compound with formula KC3H5O3, or H3C-CHOH-COOK. It is the potassium salt of lactic acid. It is produced by neutralizing lactic acid which is fermented from a sugar source. It has E number "E326". Potassium lactate is a liquid product that is usually 60% solids but is available at up to 78 % solids. Potassium lactate is commonly used in meat and poultry products to extend shelf life and increase food safety as it has a broad antimicrobial action and is effective at inhibiting most spoilage and pathogenic bacteria. Potassium lactate is also used as an extinguishing media in the First Alert Tundra fire extinguishers.

Uses

Different sources of media describe the Uses of 996-31-6 differently. You can refer to the following data:
1. Potassium DL- Lactate is used in preparation of high solids and high protein lactose-free aseptic milk concentration and milk powders with forward osmosis.
2. Potassium Lactate is a flavor enhancer that is the potassium salt of lactic acid. it is a hygroscopic, white, odorless solid and is prepared commercially by the neutralization of lactic acid with potassium hydroxide. it is used as a flavoring agent and enhancer in some meat and poultry products, a humectant, and a ph control agent.

Check Digit Verification of cas no

The CAS Registry Mumber 996-31-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 996-31:
(5*9)+(4*9)+(3*6)+(2*3)+(1*1)=106
106 % 10 = 6
So 996-31-6 is a valid CAS Registry Number.

Highly Efficient Iridium-Catalyzed Production of Hydrogen and Lactate from Glycerol: Rapid Hydrogen Evolution by Bimetallic Iridium Catalysts

Cheong, Yeon-Joo,Sung, Kihyuk,Kim, Jin-A,Kim, Yu Kwon,Jang, Hye-Young

, p. 4064 - 4068 (2020/09/12)

Mono- and bimetallic iridium complexes involving novel triscarbene ligands were synthesized and applied to the dehydrogenation of biomass-derived glycerol. This resulted in affording hydrogen and lactate with the excellent turnover number (TON; 3,240,000) and turnover frequency (TOF; 162,000 h–1). The triscarbene ligand in a single frame allowed the formation of bimetallic iridium complexes. This induced the cooperative effect of two iridium ions and rendered excellent TONs and TOFs in the production of hydrogen and lactate.

Method for producing potassium lactate from heavy-component lactic acid

-

Paragraph 0019-0027, (2017/02/23)

The invention discloses a method for producing potassium lactate from heavy-component lactic acid. Particularly, the heavy-component lactic acid is pumped into a reaction tank, potassium hydroxide is pumped in a stirring state for a reaction, the temperature of a reaction system is kept at the temperature of 40-60 DEG C, adding of potassium hydroxide is stopped when the pH (potential of hydrogen) value of a reaction liquid is 6.5-7.5, and potassium lactate is obtained; deionized water is added to a completely reacted potassium lactate solution, the mass concentration of potassium lactate is controlled to range from 20% to 25%, and a roughly filtered potassium lactate solution is pumped into a nanofiltration membrane unit for filtration; during filtration by the nanofiltration membrane unit, penetrating fluids are collected independently and then continuously pumped into a triple-effect concentration section for concentration, trapped fluids flow back to a raw material container, the feeding speed is controlled, when the content of discharged potassium lactate is controlled in the range from 60% to 63%, discharged potassium lactate is pumped into a finished product tank, and a production process of potassium lactate can be completed. The technological process is mild, the material loss is small, and the comprehensive preparation cost (not containing the cost of heavy-component lactic acid and potassium hydroxide raw material) is smaller than 300 yuan per ton.

Ruthenium-catalyzed hydrogen generation from glycerol and selective synthesis of lactic acid

Li, Yang,Nielsen, Martin,Li, Bin,Dixneuf, Pierre H.,Junge, Henrik,Beller, Matthias

supporting information, p. 193 - 198 (2018/04/16)

An efficient hydrogen generation from glycerol and selective synthesis of lactic acid (67%) using pincer-type ruthenium complexes is described. Analysis of the products from glycerol dehydrogenation indicates that improving the efficiency of the decarboxylation step is a key point for further reforming processes.
