Lithium stearate production method :

Chemical synthesis method

Lithium stearate can be synthesized through a series chemcial reactions that combine stearate and lithium metal. In order to get the two reacting fully, lithium metal is heated and the stearate root is stirred together in an organic solvant. After washing and drying, the pure lithium-stearate product is obtained.

Following are the steps for synthesis.

(1) Mix the lithium metal with stearate roots in organic solvents such as ethanol and stir them, heating, until they fully react.

(2) The reaction solution must be cooled in order to precipitate lithium stearate.

Remove the crystals and rinse them with water.

(4) The dried crystals will be used to make lithium stearate.

Chemical synthesis is characterized by a matured process, a high level of production efficiency and pristine products. However, organic solvents have a negative impact on the environment. A certain amount of waste is generated during production.

Methode de fermentation biologique

In biological fermentation, microorganisms such as yeast are used in the medium to produce lithium. The principle behind this method is that microorganisms use their metabolic pathways to produce stearic and react with metal ions, such as lithium ions, to create lithium stearate.

These are the steps that you will need to take in order to produce your product.

(1) The microorganisms will be inoculated onto the medium that contains precursor substances for fermentation cultures;

(2) The filtrate is used to produce a solution of stearic acetic acid.

(3) Add metals (such as the lithium ions) into the solution with stearic to ensure that they fully react.

(4) The reaction mixture is separated, then washed and dried.

The benefits of biological fermentation include environmental protection, less waste discharge and a longer production process. However, the conditions for production are also higher.

More than a hundred schools in the UK have been closed due to the risk of collapse

In the UK, more than 100 schools were closed because of the danger of collapse

In the UK, many schools use Autoclaved aerated cement (RAAC). This is a concrete material that is lighter.

In 2018, the roof collapsed of a primary-school in southeast England. Later, it was discovered that RAAC material had been used to build the school's roof and other buildings. This raised safety concerns.

BBC reported that RAAC materials were widely used from the 1950s until the mid-1990s in areas such as roof panels, and had a lifespan of around 30 years.

According to reports, the risk of building collapse is not only present in schools, but also in hospitals, police station, and other public structures. RAAC material has been found.

The Royal Dengate Theatre at Northampton is temporarily closed after RAAC material was found.

According to NHS, RAAC has been detected in 27 hospital building.

The NHS chief has been asked for measures to be taken to prevent collapse.

BBC reported that since 2018 the British government has warned schools to be "fully ready" in case RAAC is found within public buildings.

The Independent reported Jonathan Slater, former senior official of Department of Education. Slater said that when Sunak was chancellor of treasury in 2021, Sunak approved cuts to budgets for the construction of schools.

Nick Gibb is a senior official at the Department of Education. He said that the Department of Education asked for PS200m annually for school maintenance. Sunak, then the chancellor, only provided PS50 million per year.

The report also states that despite Sunak having promised to renovate at least 50 schools a month, only four have been renovated as part of the government's major reconstruction plan.

The British National Audit Office chief also criticised this crisis. He claimed that the Sunak government had adopted a "plaster-method" of building maintenance.

He believes the government's underinvestment has forced schools to close, and that families are now "paying the cost".

Paul Whitman is the secretary-general of National Association of Principals. He said that the public and parents would perceive any attempt to blame individual schools on the government as a "desperate attempt by the federal government to divert its attention from their own major mistakes."

Whitman claimed that the classroom has become completely unusable. Whitman blamed the British Government for the situation. "No matter what you do to divert or distract, it won't work."

London Mayor Sadiq khan said that the government should be open and transparent. This will reassure parents, staff, children, and others.

BBC reported schools in the UK were pushing forward with inspections and assessments. Children who had been suspended because of school building issues will be temporarily housed, or they can learn online.
